Am I the only one who dislike AoT? Probably...
Anyway, I suggest you watch a different kind of anime, if you want:
Here are some titles:
Higurashi no Naku Koro ni
Deadman Wonderland
Elfen Lied
Steins;Gate
Nichijou
AND SINCE YOU LIKED INITIAL D (Although not as good in my opinion):
Wangan Midnight
Bari Bari Densetsu ("Movie", motorcyle)
