The hit musical Fox series Glee had a rocky 6 years. At its height, it was a beloved high school dramedy featuring new covers of iconic songs. It was fresh and, to many, it was inspiring, with its inclusion of different kinds of people being a breath of fresh air in a world where entertainment media is dominated by straight white males.

At Glee's lowest points, however, the series was boring and cliché. Many people would get irritated by their musical numbers, claiming that they "ruined" already perfect songs. At other times, some people thought that the diverse inclusion in Glee would go too far, forcing in more gay characters in a grab for attention rather than for actual narrative purposes.

Throughout Glee's rocky run, a plethora of characters were brought in and out of the series. This variety of characters is understandable, as it was an ensemble TV show about a high school, which realistically brings people in and out every year.

While a number of these new characters were delightful additions to an already diverse cast, there were also a number of character additions that didn't add much to the show, and ultimately hurt the series. While some of these characters should have been left with one episode appearances, there were other characters that ideally should not have been part of Glee at all.

Though these characters additions may not have been the only problem that fans had with Glee during the show's lowest point, they certainly did not help the matter.

With this in mind, here are the 10 New Character Additions That Hurt Glee (And 10 That Saved It).

Hurt: Lauren Zizes

The second season of Glee tried to mix things up by adding a few new characters to the New Directions. Unfortunately, not all of these characters were as well-rounded as the others. Lauren Zizes was unfortunately one of these characters that did not receive as much depth as the others. Lauren was the first overweight character added to the diverse cast (or at least the first character whose overweight-ness seemingly defined her), adding a bit of inclusion to a demographic that is rarely seen in media.

Unfortunately, unlike other diverse characters like Kurt or Artie, Lauren Zizes received very little development, with her character frankly only being written as someone who is "overweight" and "goth."

This character certainly had a lot of potential with the show, but instead quickly became a background character that only really interacted with Puck, who only liked her for her physical appearance.

Saved: Blaine Anderson

Kurt's character arc in the first season was certainly interesting and inspiring, showing him as seemingly the only gay person in town. The second season seriously mixed things up for his character, however, and put him face to face with a number of other people just like him, showing him that he was not alone. Blaine Anderson was one of these people brought into Kurt's life, and overall, Blaine seriously helped the series.

At first, he helped Glee by being the newest addition to Kurt's side of the story, but by season three, Blaine soon became the star of the show. The writers of Glee quickly realized how talented actor Darren Criss was, and gave him a lot more focus. Blaine soon ed the New Directions and became one of the driving forces of the series, being almost as popular as Rachel Berry herself.

Hurt: Jake Puckerman

The beginning of season four added a variety of new characters to Glee, filling the gaps left open when over half of the New Directions graduated. One of these new characters was Jake Puckerman, the secret younger brother of Noah Puckerman, who at first was a welcome addition, but soon hurt the series. When Jake first showed up, he was a unique character. Throughout the fourth season, Jake had a tug-of-war battle inside of him between doing the right thing and the wrong thing, taking a good portion of the spotlight as the season went on.

Unfortunately, his character became an absolute waste by season five, when the writers decided to take him down the road of being a "bad boy." While this created new conflict, it ultimately ruined his character. While Jake's character arc may have started out as interesting, the decisions made for him as time went on proved his entire arc to be an absolute waste of time.

Saved: Sebastian Smythe

By the time Glee reached its third season, many fans were subconsciously longing for a new antagonist besides Sue Sylvester. While Sue was certainly a great villain, she had been in that position for two years, and a new antagonist needed to be brought into the picture, at least for a short amount of time.

Sebastian Smythe, the new leader of the Warblers following Blaine's departure from their school, ended up being the perfect antagonistic addition to season three.

The fantastic performance given by Grant Gustin made Sebastian into a rather formidable foe, serving both as a threat to the New Directions and to Kurt and Blaine's relationship. Sebastian wasn't just great because he was a villain, however. As time went on, Sebastian eventually redeemed himself, having a well written arc by the end of his run in season three that turned him into a respectable character.

Hurt: Becky Jackson

The first episode featuring Becky Jackson was perhaps one of the best written episodes in the entire series. It opens revealing that Sue has taken Becky under her wing, with the New Directions worried that Sue is just getting close to Becky in an attempt to embarrass her. By the end of the episode, it is revealed that Sue actually had a sister with Down's Syndrome and that she did care about Becky.

Unfortunately, as Becky continued to appear throughout the series, her character became more and more flat. While her interactions with Sue would occasionally be heartwarming, her interactions with the rest of the cast felt off and didn't add at all to the series. When she wasn't in Sue's office, Becky was written as "mean" and was at times even patronized by other characters in the show, ultimately undoing all of the progress that the show had previously made.

Saved: Brody Weston

Season four of Glee took Rachel and Kurt into the heart of New York City, where they both faced new conflicts and obstacles in order to succeed. One of the most well done conflicts for Rachel in this season was her relationship with Brody Weston. While most people didn't really "ship" Brody and Rachel, this was actually a good thing. Since season one, no one really doubted that Rachel and Finn were supposed to be together.

Brody Weston quickly became the best barrier between Rachel and Finn since Jesse St. James in season one. Even though it was clear that Brody was bad for Rachel, she stayed with him anyways, and even a good portion of Glee fans found themselves giving up on "Finnchel" during Brody's run in the show. Though many viewers hated Brody and what he turned Rachel into, he still brought with him a fantastic arc. Brody Weston truly did bring a lot to the table.

Hurt: Spencer Porter

The final season of Glee arguably redeemed the previous two disappointing seasons, adding a variety of new characters to the ensemble and bringing the series full circle. While a majority of these new characters brought something new to the table, the character Spencer Porter was ultimately a disappointment. Spencer was both a "jock" and gay, which was a type of character that the show hadn't really focused on much.

While Spencer certainly had the potential to add something new to the show, he wasn't written well.

The writers couldn't seem to find out how to balance the two sides of his character. To add to the matter, actor Marshall Williams didn't have the best singing voice. However, this may not have been his fault, as it seemed as though the showrunners and writers kept giving him songs that were noticeably out of his vocal range.

Saved: Coach Beiste

Following the departure of Coach Tanaka after season one, Coach Shannon Beiste was added to the series. The inclusion of Beiste ended up becoming one of the most eye-opening aspects of the series, from season two all the way until season six. When Beiste first appeared, her interactions with other characters ended up starting a huge thematic element about bullying. The of the New Directions found themselves making fun of Beiste for how she looked, despite all being misfits themselves.

By the final season of the show, Beiste's character had received quite a bit more development and was now seeking to receive a gender change. The way the writers handled this arc was actually fantastic and eye opening. From beginning to end, Coach Beiste was one of the best character additions that Glee ever received.

Hurt: Sam Evans

Though he was a fun character who stuck around from season two until season six, Sam Evans was ultimately a failed character for Glee. When he first appeared, he was treated like a newer Finn, but as time ed, his character development ended up becoming bland and repetitive.

Rather than being an active character with strong motivations, Sam soon only became a love interest for nearly every female character throughout the show's main cast. As time ed, the writers must have realized how bland and unmotivated they had made Sam. However, instead of fixing the issue and adding more depth to him, they instead did what they did with Brittany and wrote him as an incompetent, which somehow served as an explanation for every unnatural decision made by his character throughout the series.

Saved: Kitty Wilde

One character addition in season four that paid off long term was Kitty Wilde. Kitty was added as the new Quinn, being the mean Cheerio who ends up ing the New Directions and showing her lighter side, and ultimately sured Quinn as a character. Kitty's first few episodes showed her as a rather bland character, being just another mean cheerleader.

However, as time ed, Kitty revealed herself to be a kind-hearted spirit who actually consoled a number of her colleagues.

By season six, Kitty became the student leader of the New Directions, serving as a fearless leader who welcomed the diverse new in a natural and inspiring way. If the writers had handled Quinn the way they handled Kitty, perhaps Quinn would have had a larger effect on the series beyond season one.
