I understand it is two extremely sensitive homos who give the sheep a break by getting it on with each other.
I saw Medved on O'Reilly's show a couple of nights ago, and he referred to it as "the infamous pup tent scene". He said he saw people (his wording seem to indicate men) walking out of the film at that point.
He seemed to think that this film had gotten so much publicity that everyone should have known what they were getting into. Personally, I don't think people pay all that much attention to film reviews. They may have heard "gay cowboy" without knowing that you were going to be given a very up close and personal look at what actually goes on between two "gay cowboys".
