+19
Yeah, here we go! I'm expecting a bunch of my picks to start showing up and here are two of them. In general, the best parodies are the ones that most clearly embrace their source material. They may be poking fun at it, but with love. Two great examples of that here.
My #20, Shaun of the Dead, can (and does) function as a horror film even when it's pulling at the threads of the genre. It exuberantly embraces its roots while cheerfully mocking its conventions.
GalaxyQuest, my #9, does this with perhaps even more affection and joy, if that's possible. It's pretty clear that nobody loves Star Trek--and its attendant fandom (back in those halcyon days before the internet got hold of everything and ruined it)--more than the people who made this film. Looking back, it's kind of a perfect little coda to a time when loving something was more important than guarding it.
