Jesus, this question is unfair. Why do I have to pick just one? I like too many movies, dammit.
Well. I guess if I have to pick just one, it'd be one of the following: Little Miss Sunshine, Saved, or Muppet Treasure Island. The plot synopses are pretty simple all around, really.
- Little Miss Sunshine: The Hoovers are on the brink of bankruptcy and their lives, collectively, suck. Cheryl is constantly stressed about money; her teenage son Dwayne has stopped speaking until he can join the air force as a test pilot; her second husband Richard is a failure of motivational speaker and generally irritating; Richard's father got kicked out of a retirement community for snorting heroin; and her brother Frank (a Proust scholar) just attempted suicide; after losing the young man he fell in love with and a genius grant to Larry Sugarman, whose Proust scholarship is not as awesome as Frank's.
At the center of this is Cheryl and Richard's daughter, Olive (7), who wants to be a beauty pageant queen. She's rehearsing for the Little Miss Chili Pepper pageant in Albuquerque when it turns out that, because she was runner-up in California's Little Miss Sunshine pageant and the winner had to forfeit, Olive has a place in the state finals in Redondo Beach. The entire family goes on a road trip to get her there. Dysfunction ensues, drama ensues, hilarity ensues, and everybody learns that it's okay to be a freak, as long as you're making yourself happy and you have people to love. - Saved!: Mary is a born-again Christian and going into her senior year at American Eagle Christian High School. She has it all, except that ... whoops: her boyfriend, Dean, thinks he's gay. She tries to turn him straight, which culminates in intercourse that gets her pregnant (which, at first, she really hopes is cancer). This leads her to question her faith, as well as all of her life plans, and when she ends up ostracized from her friends for "turning away from Jesus," she finds unlikely allies in the rebellious Jewish girl, Cassandra, and self-professed atheist, Roland. Oh, and Patrick Fugit plays a skateboarder named Patrick, who really wants to go out with Mary and is so open-minded that Mary finds trusting him hard. Oh, and Mandy Moore is amazing as Hilary Faye, Roland's sister and Mary's ex-best friend, who walks a very fine line between hilarious and horrifying.
Oh, and Mary's mom is: a. a MILF, and b. sleeping with Patrick's dad. Who is also the school's pastor. Hilarity ensues. ... See this movie, if you haven't. - Muppet Treasure Island: ... it's Treasure Island. WITH MUPPETS. Also, Tim Curry. ... That's pretty much all there is to it, and it's AWESOME.
