The franchise adds a group. The cheer captain and the zombie are now the establishment, which is a small interesting turn, and then the film repeats the welcome. Songs, a crush, a secret identity, a final number in which the town's fear is embarrassed into silence.

Unnecessary if the first was seen and discussed. Harmless enough for the same age. A house does not need four variations of a poster. One honest conversation about a real new kid in a real school is worth more.
