Ladies and gentlemen of the jury, take a looksie. At "Catfish."

I happened to stumble upon this trailer on the Apple trailers site. The caption was "Don't let anyone tell you what it is" as in, watch the damn thing for yourself and make your own conclusions. Fair enough. 
From what I know, Sundance audiences and critics have been raving/spreading the word about this mysteriously enticing film that looks interesting at first, and then seems to take an extremely unexpected turn at the very, very end.
It's a mockumentary, one of my most beloved genres. It's an exciting art to take on, almost as raw and exhilarating as watching a play with the actors in front of you, in the flesh, nothing to hide behind. I am very intrigued to see this entire film considering how choppy the trailer is and gives almost nothing away. Like one little hint would spoil the entire ending. The latimesblogs.latimes.com has a complete article on the film here: http://latimesblogs.latimes.com/the_big_picture/2010/01/sundance-fever-what-catfish-says-about-our-247-video-age.html
(I haven't mastered linking yet so bare with me.)
Watch it.
