Really good, but with two main flaws (spoilers)
(1) When they let the bus people in and don't cotton to the fact that the heavyset woman was, as someone on another thread put it, an "obvious zombie". Ana had seen her husband/boyfriend get bitten and turn! At least no one died from that mistake.
(2) The erasure of hope during the end credits (which, as a kind of cruel joke, is called "Credits/Hope" in the chapter menu on the Blu-ray). This group went through a lot, including losing not only redshirts but a couple of their most charismatic members. Let us at least imagine that they might have made it, c'mon.
