I've been hearing the whole laughing out loud thing in regards to this series, yet I haven't been. Maybe what I think is funny is different (And hey, it happened during the first season of Girls too, and now I think that show is shit) but I thought this was a drama, with a little comedy overtones thrown in.
A lot of that humor comes out through some of the characters. Caputo is mildly funny in a sleazy sort of way and Mendez acts like he's from a Cops
parody or something.
