“Kindergarten Cop 2” (*** out of four) was a cute direct-to-DVD sequel to the Arnold Schwarzenegger 1990 favorite about a gruff FBI agent (Dolph Lundgren) assigned to go undercover as a kindergarten teacher in order to retrieve some stolen data and stop a threat to their town. Lundgren has never been more likable and winning, and he carries this very unnecessary but entertaining sequel. Not quite as intricate or funny as the first but better than most other sequels made 26 years after the original.
