But the fundamental flaw with this, in my opinion, is that this isn't really a 'plot.'
You’re right. It's not a plot. It’s a
point, as answered to the OP. Further, Sybok being a false prophet is a theme, and his misadventure of “not really going to find God” becomes an arc, and an integral part of the plot.
We already know that Sybok is a false prophet and that he's not really going to find God. So there's really nothing for the audience to be convinced of. I mean, was there actually someone in that theater watching the film who actually thought Sybok was right and that he would actually find "God" at the end of the film?
Probably not. I (as I’m sure you and most others) kinda had an inkling that Sybok was not going to land on his feet by the credit roll. Nothing was going to convince me otherwise. But that journey makes for excellent drama, and plot, doesn’t it? See
Don Quixote. Not exactly the same, but quite similar. We know that a flawed character on a quest will usually be disappointed, at the least. That trope is an old chestnut.
I know: not for you, in this particular case. Fair enough. Though, I think you’ve confused “point” with plot. And character arcs and story arcs.
Yes, I'll agree that the McCoy's and Spock's respective dads' scenes were pretty moving. But they were really nothing more than just reinforcement for a film about Kirk being strong while literally everyone else around him was weak.
I don’t think so. That’s an oversimplification. It showed Kirk being the type that channels his pain into motivation. It’s what gives him the capacity to captain a starship. Also, the scene did not show McCoy or Spock as weak, but strong despite their pain. Scotty wasn’t weak, either, by the way.
I think you're giving the concept of TGB far more credit than it actually deserves, since if it was supposed to be a 'test of faith' to get through it, then how did the Klingons and their clunky BoP fly through it just fine?
The Klingons got through it because they had faith that they’d get through it. It wasn’t as though “faith in our Lord and Saviour Jesus Christ” was literally the key that unlocked the door. It was Kirk’s (and Sybok’s) faith in himself that he could endure and conquer the unknown. Same with the Klingon commander. It’s explicit in Sybok’s dialogue.
KIRK: You can't expect us to stand by while you take this ship into the Great Barrier.
SYBOK: What you fear ...is the unknown. The people of your planet once believed their world was flat. ...Columbus proved it was round. They said the sound barrier could never be broken. ...It was broken. They said warp speed could not be achieved. The Great Barrier is the ultimate expression of this universal fear. It is an extension of personal fear. Captain Kirk, I so much want your understanding. I want your respect. Are you afraid to hear me out?
KIRK: I'm afraid of nothing.
I think the
concept of the Great Barrier is sound. It’s possible that it is the execution that finds The Final Frontier wanting.
If I sound like I'm nitpicking, I apologize. As far as I'm concerned, if you liked TFF, then great, and more power to you. And if the above points work for you, that's awesome. They just really didn't work for me the same way.
I get that it didn’t work for you, and I don’t think you’re nitpicking. The problem is you’re disassembling the points, arcs, themes, and story lines all wrong.
