There is absolutely nothing wrong with the concept of STV: it's classic "Kirk meets "God"". And acting wise, it's really not that much different, again, than TOS. The problem is, Shatner isn't that good of a director and it was really poor execuetion that killed the movie. There were some wonderful character moments: The campfire scene-- which is one of my top 10 'Trek scenes ever cause it was so much of a "tired old warriors" moment, the final scene in the lounge with them all in front of the ship's wheel, Even Sybok isn't a bad character (in concept). The problem is that the story was bigger than the way they went with it.
Well said.
