"Birth" is a little weird, airing over only a fourth of the way through the season and being entirely set in the past. The episode has some good moments with Chris and Regan, less Ava than usual, and their lives before the baby, but it's a birth. How funny can a birth be, and how complete can a plot about a birth be? Up All Night isn't a show where things quickly spiral out of control and go crazy, so there's no much going on other than the birth, which goes along with a few snags but otherwise is normal.
Score: 8.4/10
