These anime series are incredibly hard to pull off, but when they're done successfully, they're always a hit.

The best philosophical anime series tackle themes other series might be afraid of including in their stories. These thoughtful series aren't afraid, however, and dive head first into some of the most thought-provoking and mentally stimulating ideas any anime can feature. If a particular show or movie can ask and answer these complicated questions well, they almost always stand head and shoulders above any other anime in their genre.

Puella Magi Madoka Magica is one of the most deceptive anime series around. On its surface, it's a wonderful anime about magical girls and the fun times they have together. After just a few episodes, however, Madoka Magica leaves viewers wondering what they just saw. Without giving too much of the plot away, it quickly shifts from a happy-go-lucky series into a brutal, dark anime that few can forget.

What makes Madoka Magica stand out are the surreal themes it faces. After convincing viewers that it's just an entertaining, lighthearted series, it becomes clear that Madoka Magica is anything but easygoing. The fact that the first impression the anime leaves viewers with is so much different than what the series actually turns out to be is a huge part of the series' surrealism. Nothing is as it seems in the world of Madoka Magica, and that's the best part of the show.

Netflix has made Tenma’s legendary search for Johan accessible to a brand new audience. Here’s why the classic mystery Monster deserves a watch.

Monster takes a while to pick up steam, but that's only because the series takes a lot of time with its deeply philosophical themes. One of the biggest themes the show features is nature vs. nuture, unpacking whether a person's true nature is something that can be changed or if it's inherent to who they are. While the show doesn't provide any answers, it does provide a ton of questions to keep any viewer guessing long after the final episode.

Code Geass is an anime about how even when everything seems to be perfect, things can still unexpectedly go wrong, and how unlimited power can be more of a curse than a blessing. The character at the forefront of the action is Lelouch Lamperouge. He's gifted the powers of the Geass early in the series, giving him the ability to make anyone follow his bidding by simply looking at them and telling them what to do. While this may seem like a simple enough premise on its surface, it quickly turns into a complicated disaster.

Code Geass shows that not everything goes well, even with absolute power. Lelouch starts the series as a near omnipotent being before falling victim to the same power that earned him the position he sought after. Even after putting several important pieces into play, Code Geass proves that getting everything one ever wanted is hardly for the best.

Steins;Gate is all about time travel. Main character Rintaro Okabe bit off more than he could chew when he inadvertently invented a time machine with his friends. Some of the most gripping themes that the anime tackles include PTSD, time travel, and fate itself. Even though the main characters are some of the smartest in anime, even they are helpless to fate itself, often traveling back in time again and again to prevent events that feel inevitable.

Out of all the deep, philosophical anime series out there, Re:Zero - Starting Life in Another World might be the most brutal. The series surrounds Subaru Natsuki as he looks to navigate the new world he's transported to. While it seems idyllic on its surface, Subaru's new world does not actually fit this description. He's met with challenge after challenge, dying several times before he can even get a grip on the new reality he's faced with.

Re:Zero is one of the best series in the isekai genre that is so much deeper than it appears to be. Subaru faces themes of hope, fate, and more in Re:Zero. He never knows what the right answer is, which is ironic given his ability to Return by Death. He often finds the correct path, only to be met with increasingly cruel deaths that slowly chip away at his sanity as they occur over and over again.

​​​​Not only is best anime series of all time. It's hard to describe what Neon Genesis Evangelion is about precisely because of how deep it is. At its core, it's a story about Shinji Ikari, a young boy summoned to pilot the Evangelion units in an attempt to defend what's left of humanity from the Angels looking to tear everything apart.

Neon Genesis Evangelion will make a viewer think about things that they've never thought about before. It explores themes of hope, justice, and what it means to be real. To call it confusing is a massive understatement to many in the best way possible. It's a series so deep and philosophical that watching it a second time might not even provide all the answers that viewers are looking for. It stands alone as a twisting, winding series that keeps its viewers on the edge of their seats during every single episode.
