As for the new movie, I have moved my review to the other movie thread.
Star Trek V had a great premise but was horribly written and directed NOT to mention the special effects. The special effects were cheap looking and needless to say I don't think that SFX house has done much since.
It bit it's own hand (a no no in film making). You don't make fun of your self. Think Gremlins II, you never go Gremlins II on a movie. This is where you take all that made the first movie unique and make fun of it. Star Trek V had Scotty banging into bulkheads, Kirk sitting on a toilet like he's taking a crap, characters acting completely out of character .A completely uninteresting actor playing "the villian" in Sybock.
