The story takes place in 1994 New York, where the Autobots join forces with the animal-shaped Maximals to face Unicron, a planet-eating villain. Fans of the Japanese series “Beast Wars” will be happy to see these characters appear in a Hollywood film for the first time. Director Steven Caple Jr. sets the action seven years after “Bumblebee,” giving the series a new feel. The movie blends old memories with new ideas, but it delivers only about 60% of what fans might hope for.
