Well, I'd have to say that Galaxy Quest is one of my favorite movies. I think you have to be a serious dyed-in-the-wool Star Trek dork to really appreciate Galaxy Quest. But that's the beauty of it, even if you don't know that much about Star Trek, it's still just a fun adventure movie. But if you love ST, then you know just exactly how funny the parody is. Tim Allen is dead on as a WIlliam Shatner/Captain Kirk-esqe guy. He basically a good-hearted, happy-go-lucky guy, and he doesn't really realize that he has a giant ego and that his ego often annoys or even really hurts the feelings of his costars, who are equally if not more talented. Alan Rickman is brilliant in the Spock-Like role. He does aggreived so well. And the parts where he declares that he's quitting or committing suicide are just hilarious. Then there's the whole discussion of the nature of stories with the child-like, incredibly literal-minded aliens, who that the Galaxy Quest show is real and that the episodes constitute historical documents. Our guys go along with it at first, but the bad guy forces them to dissolution the friendly aliens. It's a tremendously effective horrible moment. It's like telling a bunch of little kids there is no Santa Claus. It leads to one of the most heart-rending moments when the alien assigned to Alan Rickman's character is killed in action and he tells AR's c that he's just honored to have know him. Then I love the bit at the end when the teenage uber-smart dorky fans are helping the Captain and Sigourney Weaver's character through the bowels of the ship, which the kids know better than the actors because they have a more thorough knowledge of the "schematics" of the "ship." Tim Allen's character says, "It was just a chair on a set! With Christmas tree lights!"
