XX/XY feels undone.
Take the male adolescent fantasy of bedding two females and hopefully watching them bed each other, throw in some complications, and see where it takes us, is essentially the crux of this movie.
Unfortunately, despite the excellent camera work and sharp performances by the cast, something is missing in this screenplay in order for us to empathize with these characters. It's as if the writer wanted to give everybody equal screen time, but forgot to flesh out the true love interest--Sam, played nicely by Maya Stange. If Maya were further fleshed out as a character, the audience might actually feel satisfied by the end of this so so movie.
Too bad. There is a diamond in the rough here...but it is buried in shallowness.
Speaking of shallowness, considering the constant state of free love depicted in the movie, nobody seems concerned with STDs or AIDS. What's up with that?
