One of the things I like the most is how each character develops, because they explain the background of each one. And the other thing is that I like the turn of the story, the way Eren wants to kill the titans, and then all that series of events happens to him (I'm not saying it to avoid spoilers).

The animation is great too, as they animate each Titan, it really is great. Each time the plot makes more sense; I see it as a kind of puzzle, the more you see, little by little each of the pieces fit into place. Is incredible
