Why were the TOS movies better than the TNG movies? - Star Trek: Website

(Not including the reboot trilogy as that’s a different altogether topic) I was recently in a mood to binge the first ten Star Trek films as I hadn’t seen any of them in several years, and I notice that the TOS films are better than the TNG films. Which is weird because when it comes to the tv series, I far prefer TNG and its spin-offs over TOS but when it came to the films, it’s the opposite. I love First Contact, and like Generations but Insurrection and Nemesis are pretty bad IMO, whereas the only TOS film I truly dislike is V. (My favorites are IV and VI) Was wondering what others here thought, I think this may be the standard opinion in fact. As for why they’re better, I think for whatever reason the TOS movies feel more cinematic, whereas the TNG films were mostly trying to capture the TNG feeling and not as much be cinematic?

It’s the even numbered movies that are good (2,4,6, First Contact, Nemesis). There’s even a TVTrope about it.
