Star Trek IV: The Voyage Home (1986)
I didn’t expect much given the ludicrous premise, but… I loved it. William Shatner got his acting chops back, and each member of the Enterprise got something to do. I did wonder though, with all the times they show off their futuristic tech, why didn’t it result in another alternate timeline? But that’s a minor quibble. The movie was charming and irreverent.
