They were good once. Great, in fact. Shit like Death Note and Black Lagoon are damn fine shows. However, something happened just before 2010, and their talent really started to wane off. Now that all of their talent is over at Mappa, they're now a terrible studio.

Yeah I'm sure at least all of Madhouse's talent is required to make 3 seasons of Teekyu.
>a terrible studio
Can you even name more than 2 works they produced since 2010; before spouting such bullshit?
