Anytime a young adult (or YA) fiction book becomes blatantly popular among young readers, there is a high chance it will be turned into a movie. Sometimes, it will even be turned into a franchise. The movie's success is almost predetermined, and this is not uncommon.

YA movies are extremely lucrative, with loyal fans visiting theaters numerous times to see their favorite characters come to life. While Harry Potter may have prompted the book-to-screen era, it was Twilight that allowed YA novels to suddenly come to the limelight and take over movie screens. Twilight made nearly $70 million in its opening weekend alone. The series caused a massive frenzy; ultimately leading to a slew of other YA adaptations to follow suit. That brought about the birth of The Hunger Games, and Divergent, just as some examples.

While these movies have die-hard fans, it does not stop critics from expressing their honest opinions. Even with all of the commotion around Twilight, it only garnered a 49 percent rating on Rotten Tomatoes. To some critics, performances in these films are lackluster. In some cases, they are just plain embarrassing. So embarrassing, it is probably best to forget about them altogether. Although fans may be able to turn a blind eye, it is hard for average viewers to see anything other than train wreck performances come out of these popular adaptations. On paper, these characters are complex, on screen they are laughable.

Here are 20 Characters YA Adaptations Want Everyone To Forget.

20. Kristen Stewart - Bella Swan

Despite being loved by many young teens at the time of its premiere, it is no doubt critics were harsh on Twilight, more specifically, Kristen Stewart. If people had a hard time with Bella's character in the book, the movie adaptation did not make it any better.

Bella Swan seemed to be Kristen Stewart in her natural habitat: awkward and deadpan. Although it worked for quirky Bella in the novel, on screen it was off-putting. It even landed her the Golden Raspberry Award for Worst Actress. All things considered, Twilight made Kristen Stewart a household name, along with her costars. However, that still does not stop anyone who watches the YA adaptation from cringing at the sight of Bella's blank stare.

19. Shailene Woodley - Tris

It seemed like 2014 was going to be a big year for Shailene Woodley. After all, she was slated to star in two much-anticipated YA adaptations. While not a dry eye was left in the theater after watching The Fault in Our Stars, critics were not as pleased with her performance in Divergent. Woodley played Tris, a 16-year-old who lives in a dystopian world where its citizens were separated into four distinct factions.

After finding out she is divergent, a mix of all four factions, Tris needs to hide her plight from the world for fear of being discovered. She then chooses to leave her "stiff" roots of Abegnation behind and s Dauntless, the fearless faction. Critics, however, thought her performance was just that: stiff; having a hard time differentiating between her innocent former self and her nnewfoundDauntless persona.

18. Johnny Depp - Grindelwald

It's no doubt that Johnny Depp is a decorated actor. However, after controversy around his past arose, it tainted his role as Grindelwald in the Harry Potter spin-off Fantastic Beasts and Where to Find Them.

The actor reprised his role in the newly released sequel Fantastic Beasts: The Crimes of Grindelwald much to the dismay of critics and fans everywhere. Needless to say, people were underwhelmed by his performance in the new movie. The Independent.ie described his performance as "impossible to take seriously, and leaves a gaping hole that a menace on the scale of Ralph Fiennes’s Voldemort should have occupied." It also asks if Depp has "forgotten how to act."

17. Harrison Ford - Colonel Graff

To most, the movie adaptation Ender's Game was a far cry from the book and an overall disappointment. Many thought the movie was far too rushed to be understandable.

What was more surprising, was how unenthusiastic veteran actor Harrison Ford portrayed Colonel Graff. Critics felt Ford did not add any specific dimension to the character and could have easily been ed off to any other actor. Empire wrote of Ford's performance, "It probably takes an actor as charismatic as Ford to get away with it, which he does, barely." His stagnant performance made for a forgettable role, which could have had great potential.

16. Robert Pattinson - Edward Cullen

Not only do viewers want to forget about Robert Pattinson's time in Twilight, but Pattinson himself also wants to forget. He is arguably one of the toughest critics on the franchise and is the most outspoken cast member when it comes to the movies.

The actor has been seen many times poking fun at his role as the brooding, overly-pale vamp, and critics of the movie do just the same. In a review of the popular teen film, Slate stated, "Pattinson, a British actor chosen for his sculpted face and gazellelike physique, doesn’t seem to have been given much direction beyond 'melt the camera with your eyes.'" It also goes on to say that Edward, as portrayed by Pattinson is "no one you’d want to risk your immortal soul for, his worthiness doesn’t really matter." Much to the dismay of "Twi-hards" everywhere. His role as Edward was definitely not one of his finer performances, and Pattinson will probably be the first to it that.

15. Logan Lerman - Percy Jackson

Here is just one YA adaptation that went to the franchise graveyard. Percy Jackson & The Olympians: The Lightning Thief had all the makings to be the next Harry Potter: a huge fanbase, hot actors, and a decent plot. It tried to, even coming out with the sequel, but did not end up taking off.

Critics at The Washington Post lend its flop all to the film's casting. "As played by Logan Lerman, Percy is a pretty boy with good hair but no discernable interior life," it said of Lerman's performance. "The special effects have more going on behind their eyes." Unfortunately, many also pointed out that the movie failed to stay true to the plot of the novel, which ended up leading the franchise to its demise after the second film.

14. Nicole Kidman - Mrs. Coulter

When The Golden Com hit theaters in 2007, it was not without controversy. Groups like the Catholic League for Religious and Spiritual Rights were displeased with the movie; calling it anti-Christian and pro-atheist.

Here, viewers got the chance to see Nicole Kidman play the villain, Mrs. Coulter, whose desire is to take children for laboratory experiments. From what audiences could ascertain, even Kidman's acting chops failed to bring the mundane script to life. Overall, audiences were not satisfied with her portrayal. If viewers were not too busy focusing on the CGI, they were focused on the script that did not manage to bring out the good parts of the novel.

13. Zoey Deutch - Rose Hathaway

In 2014, Vampire Academy became just another drop in the fantasy YA adaption bucket. This time the story centered around a school for, you guessed it, vampires. It stars Zoey Deutch as Rosemarie Hathaway, who is half human and half vampire.

Critics equated the film to a mash-up of Mean Girls and Twilight, and it received a mere 17 percent on Rotten Tomatoes. Entertainment Weekly said Deutch's "snark is worse than her bite." It is also probable that the film's script was poorly written and, overall, cheesy.

12. Jim Carrey - Count Olaf

The A Series of Unfortunate Events novels were a huge hit among young readers everywhere. So, naturally, the movie adaptation would have to be popular, especially with a cast that included Meryl Streep and Jim Carrey. However, this turned out not to be true. With a gross USA total of nearly $119 million and a budget of roughly $140 million, the film didn't end up doing so well.

Jim Carrey is widely known for his improvisational skills, but many critics thought it did not work out in his favor in this instance. A 2004 review on Reel Film Reviews called Carrey's performance distracting and "there's no denying that his over-the-top antics become awfully tiresome almost immediately." Not only was Carrey's character choice confusing, but many critics found the choice to clump the first three books together into one film made it too rushed.

11. Brenton Thwaites - Jonas

Coming out 21 years after the source novel was published, The Giver did not live up to its expectations. Even though it had a star-studded cast on its side to hopefully skyrocket the movie to popularity, it ultimately worked to no avail.

A then 24-year-old Brenton Thwaites was tasked with playing Jonas, a boy six years his junior that is about to receive his profession assignment in a black and white dystopia where no emotion exists. Critics were ittedly underwhelmed by his performance, citing poor chemistry with his love interest. However, Thwaites wasn't the only star who received flack for his acting. Castmates Katie Holmes, Jeff Bridges, and Alexander Skarsgard were referred to as "zombie-humans" by Paste Magazine.
