Entertaining follow-up to "Child's Play" has the toy company that made the doll from the first film (which was possessed by the spirit of a serial killer) rebuilding the same doll to prove it wasn't responsible for a series of murders, as had been suggested by the news media. Of course, the killer (voice provided by Brad Dourif) still inhabits the doll and he's quickly on the loose again, looking for the boy from Part 1 (Vincent) to inhabit his body.
Vincent is now in a foster home run by Agutter. The actress who played his mother in the first film obviously wasn't available for the follow up. Although the plot isn't as good, there are some very entertaining moments, including the killing of a hard-ass school teacher. The climax, pitting Vincent against Chucky in a toy factory, is classic.
Followed by the worst in the series, "Child's Play 3," which is nonetheless a worthwhile watch.
