Prince of Persia: When pressed, this is the movie I call my favorite. I love it. To me, it's perfect. The ending never fails to make me happy (and I am very picky about endings, mind you). I've seen it over and over and over again and it doesn't get old. The music is wonderful.
The Lord of the Rings trilogy: I mean, it's wonderful. Not as good as the book, but honestly I doubt that would be possible. The story is just plain good. And the acting is wonderful and everything and I love it.
Return of the Jedi: It was my favorite movie for as far back as I can remember watching movies, until Prince of Persia and superheros happened. I love it. I love the music and the story and the awesomeness and the heroes and Han Solo and Leia and the weird alias. And the cool space-ships.
Bourne Identity: I watched this first with my brother eating gram crackers with chocolate frosting (he provided the movie and I the food). It was so fun. I love spy stuff and the guns and the nice fighting and the chases and Jason Bourne is pretty cool himself and it's just nice overall. And the theme music is cool.
