Sequel helped by the fact that the excellent Chucky doll and it's mimics combined with Brad Dorif voice still do wonders even if this now has become a movie about Chucky being an anti-hero spewing out one-liners. The ending at a factory that spews out dolls feels inspired after the rest of the film go through the motions. Good casting also help and Christine Elise is an attractive babysitter than any men would hire.
The bookends of this sequel-- both in the toy factory-- are not just its best moments but are really its only inspired ones. The rest of Child's Play 2 repeats the mechanics of the first one-- sans the psychological mystery-- with no one believing Andy at first until some characters do. It gets stale quickly. This sequel more works as a vessel to make Chucky a horror character further embedded into popular culture.
