Where to begin! Maybe by saying that this is my first review on MAL and that English is NOT my native language, so I apologize in advance for any mistake I may make!

Attack on Titan, or Shingeki no Kyojin, is (atleast for me) AMAZING. The first season of the anime got me back into anime once again back in 2013. Once that ended I jumped immediately on the manga, and boy, was that a good choice! It now sits in my top 3 manga of all time!

Story 10: Amazing and thrilling, never boring and simply one of the most complex and well written story in the medium. What starts off as a simple shonen with giant naked monsters that eat people, gradually evolves overtime as every secret of the world is discovered, evolving in what it is now, 123 chapters is: a post-apocalyptic war-psychological thriller and a Seinen (it's no longer a shonen, sorry).

Art 8: well, let's just say that if I had written this review after the first 40-50 ish chapters, I would have given this category probably a 5 or a 6, but even in it's artwork, Isayama has developed immensely. Is it the best? Of course not. But the evolution is indeed breathtaking. Try and compare chapter 1 with chapter 123 and you'll see

Characters 10: just like its story, AoT characters develop as the secrets are revealed. After the recent chapters, Eren is my 2nd favourite character of all time, just behind Guts from Berserk, And that says it all, since he wasn't that special for me for great part of the story.

Enjoyment 10: few series have given me this kind of feelings. Hype, sadness, hope, feeling of betrayal and so on. Simply breathtaking.
Isayama, you genius!!

Overall 10: it's a must read
