I just saw
Catfish, an independent documentary about an internet romance. It was surprisingly good. I recommend it.
Guy takes a picture that gets published in a paper. A bit later, he receives a painting in the mail of his picture, done by a little girl halfway across the country. It's a pretty good painting. He starts up a correspondence with this talented little kid, her mom, and ultimately her much older sister, who is his age. He falls in love with the older sister online.
The documentary follows this online romance and him finding inconsistencies in what he's hearing from this woman he's come to love, and it follows him ultimately going to meet her to find out what's real, and what's not.
His roommates are filmmakers who film everything, so they had already filmed a lot of footage of these events long before they realized there was a real story here and they decided to make it into a documentary.
