Galaxy Quest

This is such an enjoyable and fun movie. One terrific indication of a film's quality and integrity, is the reaction of the artists it satirizes: "I had originally not wanted to see [Galaxy Quest] because I heard that it was making fun of Star Trek and then Jonathan Frakes rang me up and said ‘You must not miss this movie! See it on a Saturday night in a full theatre.’ And I did and of course I found it was brilliant. Brilliant. No one laughed louder or longer in the cinema than I did, but the idea that the ship was saved and all of our heroes in that movie were saved simply by the fact that there were fans who did understand the scientific principles on which the ship worked was absolutely wonderful. And it was both funny and also touching in that it paid tribute to the dedication of these fans." — Patrick Stewart (Jean-Luc Picard on TNG)[8][29][30]

Every time I watch this movie I'm reminded of how hysterical it is and a perfectly real spoof on sci-fi nuttiness. Each actor is a perfect fit to their role, including Tim Allen as the too-big-for-his-britches captain star and Alan Rickman as the washed up serious actor whose only claim to fame is this goofy TV series.

If you're a Trek fan, this movie is mandatory viewing. It both skewers and salutes the actors and fans in a way where you know the people who made it truly love the franchise and the genre. It's hilarious, but still manages to have serious moments that feel earned, and has a moral message that feels like it came right out of an episode of Trek. The cast is superb. An almost perfect movie.
