On the commentary, it was pretty clear that he had not seen it in years or refamiliarized himself with it. (Odd, considering that he asked Paramount if he could re-cut it & add new FX) He didn't acknowledge any flaws other than the FX. He didn't seem to know that lots of folks hate the jokes at the expense of the crew & ship. He didn't seem to realize that most fans want the movies be respectful of the show & not campy humor. I truly think that all the gags with the 'little four' were almost purposefully bad so he could cut them out and have more big 3 screen time. The problem was there was not enough action or even a proper climax to make the jokes expenable. Had all the silly stuff been cut the movie would run about 90 minutes. He didn't seem like a director who wanted to restore his original vision just spruce it up with modern FX.
