The Undiscovered Country is properly amazing. I recommend it very much.
The Wrath of Khan and
The Undiscovered Country are great. Although I hate Shakespeare and I'm with McCoy wanting Chang to shut the fuck up with the Bard quotes. Why Klingon's would read Shakespeare is just ridiculous, but the film lampshades how the Trek franchise is always from a homo sapiens viewpoint by having a Klingon say it to their face.
The Voyage Home dials up the naff considerably. Yes it's a hoot and all that, but I think the majority of Trek cringe perception in pop culture comes from this film. I really like
The Search For Spock, and I actually find a lot to like about
The Final Frontier and I'd stand up for Shatner as a visual director, just not someone good with a light humour touch or spreading his budget across a whole film. I've only managed to watch
The Motion Picture once in 30 years, but I'd like to try the Directors Cut when I finally double dip into the new bluray transfers. The "Hi I'm the new bald officer, and everybody wants to shag me" introduction breaks my toes it's so cringe.
The best thing about the Harve Bennett era films are that they reduced Roddenberry in rank to Angry Memo Writer From Another Department and ignored his stupid horny teenager brain programming. What I dislike about them is that they lean a bit too hard onto Navy tropes with the stilted bridge officer dialogue that sounds like a bad
Star Trek impression. And the obsession about being "human". Fuck being a human, I wanna be an alien.
