Attack on Titan started in the magazine Kodansha's Bessatsu Shōnen in 2009 on September 9th. Currently, there are 99 chapters in the manga series and 37 episodes in the anime series. The manga series is still being updated and the anime series is on hold for its third season premiere in July 2018. The genres that Attack on Titan is listed under is dark fantasy and post-apocalypse fiction.
The anime is good. The characters have good characteristics trying to be closer to how they are in the manga but they are still missing some build up. The concept and storyline are great trying to keep the manga it keeps you in your seat and hooked each episode making just want to keep watching. The anime is proven to be good by my point but many people also believe the same as IMDb reviewed and gave the anime 8.8 out of 10 and TV.com gave it 8.3 out of 10. Overall the anime is good and does a good job of being in with the manga story but its storyline still drifts from the manga sometimes.
The manga series was and still is great, it keeps you hooked with amazing art work and storyline. The manga has been going on so long, eight years to be exact but no matter how old the manga is it keeps you hooked on every single chapter update and explains so much on how things happen. Hajime Isayama is a great artist and author and continues to update and keeps his fans happy with his manga series as they all wait for the anime to be up once more.
