I actually thought this was by far the best of the 3 episodes. I don't think the writing is too "hip" or anything like that, I can't really see why anyone would think that but if that's what you see, sorry. I think the closest comparison to the writing style is Home Movies, for obvious reasons, but I'm not just saying that because I knew going in who was involved. I think anyone who liked Home Movies and it's unique brand of dialogue should like this show too. It's character-based and just crude enough without being obnoxious, and just topical enough (the filmmaker was obviously a Michael Moore parody) without being lazy or self-indulgent. The voice work is the biggest strength though, again for obvious reasons. While everyone already loves Jon Benjamen, I really like Eugene Mirman (pretty funny stand-up comic, plays Yvgeny Mirminsky on Delocated, showed up occasionally as Eugene in Home Movies) as the son (Gene). My favorite though has to be Kristen Schaal as Louise (the younger daughter). She's easily the funniest character on the show and maybe one of the funniest of the Sunday night block.
This was also the first time I found myself saying "I really hope Fox gives this show a real chance", even though it hurts me to say that since it probably would mean the end of American Dad (god I wish they'd just get rid of the Cleveland Show).
