Star Trek isn’t really known as a comedy, and on its face, neither is The Voyage Home. It’s about the Earth being threatened by mysterious aliens, and Kirk discovering the only hope of communicating with them is via humpback whales, which are long since extinct. But somehow, combining the two results in a fish (whale?)-out-of-water comedy that’s one of Star Trek’s best films.
