It still looks good, and looking good means you spent money in post, camera choices, possibly the directors, and production design (compare CBS multi-cam sitcoms to see the differences). The show is literally no cheaper than something like Guys with Kids or Sean Saves the World (again, I only saw a couple of scenes, but it's definitely not in a low brow shooting style and looked much better than About a Boy and Growing Up Fisher to me). The Office and Parks and Recreation were cheap shows when they started. Stuff like this isn't any cheaper than any sitcom they're trying to make work, outside of actor cost. I really actually hate all the new crappy sitcoms that NBC puts out that obliterate the great NBC house style that was featured even in a terrible show like Whitney, and the only not awful Are You There, Chelsea? NBC has always stood out on sitcoms, with their look and production value, and it's only when garbage like Up All Night and The Michael J. Fox show come in that it ruins everything in regards to the NBC style, since they're just doing whatever they want.

I couldn't find who mixed it, but a friend of mine did the ADR mixing.
The show wasn't given any kind of a short shrift. They wanted it to make it, but evidently didn't feel it was good enough to try in the normal season. They probably should have used it instead of Welcome to the Family, but NBC isn't exactly known for making good decisions with both good and bad shows.
