I agree with everything you said. i like the movie. A lot. it was good indie movie - right what i was expecting. As to sex scene i was left with impression that it was their attempt to buy their movie cos you know - there was sex and people kinda like it. I think it was unnecessary scene. Don't know what else you don't like though :)
But all in all i didn't regret buying dvd.
And as people say you can buy dvd from BB right now if you want yoy just have to spend more money for it (rent plus dvd price).
