Less Sybok and more camping scenes would be good, but I suppose that is probably not going to happen.
I felt Sybok was the most effective thing about the movie.
How is it the Directors Cut if the director of the film didn't work on it?
Technically I guess it isn't, but maybe the people who did edit it did so according to Shatner's notes and recommendations -- sort of like how Superman II: The Richard Donner Cut
is actually the Michael Thau cut in consultation with Donner.
