Network shows don't usually get credit for being on the level of prestige networks, because usually they are not. I think this one is, and should. Some people say they have been put off by the cutesy-ness, or "forced quirk." I never got those particular vibes from the show; I thought the jokes were funny and the people were unforced in their quirkiness. Regardless of your opinion, it turns out that the atmosphere of the show is there for a purpose, and...wow.
I enjoy every character. I usually can't guess the plots. (I'm a sad lazy couch potato, so I have some experience with plot-guessing, ugh) The humor is original. "Smart" shows usually aren't that smart. This one is smart all on its own, instead of just telling you all the time about how smart it is. It does the relatively rare thing of being a show worthy of, and calling out for, a rewatch. I am excited they got the go ahead for season 2. I hope they win all the Emmys.
