One of the great manga that I ever read, I am sure many of you would say i'm exaggerate but we speak about facts, first of all, the idea seem to be new and good I mean we never watch or read a manga were the human are nearly exticted by giant man-eating beasts, second, and this is important the main character (eren) is nothing like other shitty MC who believe in ideals, nothing is ideal in this show, beside the good and the evil are not absolute, you can't speak about devil here, sometimes you get shocked by what eren can do, but you can't blame him you understand him and you understand what other think of him, because you feel what every single character feels.
the developpement of characters is pretty good, eren, and his freinds, grow in a fantastic way but I would say also I am worried about mikasa because she still attached to eren (until recently), and levi who do nothing but fighting the beard man (zeke).
the Art is pretty good, I can't give that 10/10 but I think 8/10 is pretty fine and good.
isayama say himself that h' s not a verry good artist.

finally I wanna say I enjoy this show, the atmospher, the developpement, the story and everything, so Isayama Hajime let's continu like this and thank you for this masterpiece.
