TFF was always regarded as pretty lame, and was the first and only time TOS movies disappointed me. That said, it’s grown on me an lot over the years for what it is, warts and all. I’d actually rather watch it than any of the Kelvin or TNG movies (even the one with the Borg sex lady). It kind of captures the spirit of latter TOS, both the good and the bad.
Some great suggestions on this thread. For a start, tone down the slapstick humour and all the nonsense about the Enterprise being a gitchy mess (did starfleet suddenly forget how to build ships?). No rocket boots—absolutely NO ROCKET BOOTS! Keep the warm character scenes though, loved seeing them interact off duty. Still weirded out by the Scotty/Uhura heavy flirting though.
Far too much of the budget spent in the earlier scenes on Paradise City. Let’s cut the three boobed cat lady who Kirk, completely unfazed, actually kills by simply throwing her into a shallow vessel of water. Uhura’s fan dance is also very embarrassing and, to me, demeaning to the character. I’m still amazed Nichelle Nichols actually loved the scene.
Sybok had such potential and I like the fact he’s not your standard villain but actually is the hero of his own tale. But he really needed development. Let’s see the “God entity” commune with him in visions throughout, and be convincing too. Make us wonder if he’s not actually right, after all. As someone said, make it so he’s been planning this for years and knows how to modify a starship to get through the Great Barrier—and make that scene far more dramatic than just ten seconds of characters looking somewhat nervous.
The finale needed more and better sfx but it also needed to be fleshed out significantly. It’s incredibly rushed. We never explore exactly what this being is, or how and why it locked onto Sybok. It’s just so undeveloped and reads like a rushed first draft. It’s not a particularly satisfying story and the payoff isn’t quite there. The best thing about it was the discussion about Kirk not dying there because he was “never alone”. I swear, it’s the interaction between Kirk, Spock and McCoy that gives this some real heart.
I’ve never read the novelisation but it sounds like it does address some of the scripting deficiencies and adds to the story.
