Attack on Titan. By FAR one of the best series I have ever experienced. Despite its psuedo mecha feel, I still dont class it as a mecha due to the fact that the titans, while they may be relevant for the sake of story, dont appear enough to warrant any dominant mecha feel. That, and Titans are not robots/made of steel.

Animation 10/10
Soundtrack 10/10
Story 10/10

Currently watching Monster. Getting really interesting.
