As a first episode, and very much a setting everything up episode, I enjoyed it; made me laugh and want to watch more, so job done. If anything I thought Samberg's character could have been crazier, but then maybe that would be too cartoonish. Some of the swearing seemed to stick out a bit, maybe I'm just getting old.
Looking forward to seeing more.
Oh, and that Outnumbered guy seems to have slimmed down a lot. Not that he was fat in the first place.
