Star Trek Movie Rule #1: The even-numbered Star Trek movies are always better than the odd-numbered Star Trek movies.
Star Trek Movie Rule #2: If members of the cast sing in a Star Trek Movie, be afraid. Be very afraid.
Star Trek Movie Rule #3: If the Director of a Star Trek movie also stars in the movie, he'll give himself some really hammy and gratuitous scenes.

"Everybody has an opinion on Star Trek, but there is one pattern that most people seem to agree on — when it comes to the movies, the even-numbered ones seem to be the best. For whatever reason, the odd-numbered Star Trek films seem to be the ones that get, once in a while, viewers and die-hard fans really pissed off."
