I believe that this was a well intentioned effort although it leaves a gay viewer with the desire to do harm to at least one of the principals both of whom are doing their best. Brian A. Green does a very good job of shedding his light weight past so to speak and Bret is working double time to achieve some kind of pathos.
The proclivities demonstrated are very, very real and if only Fight Club had gone there. The marriage of hand to hand combat (most of its forms) and homo-eroticism is not an uncommon theme. This was a good, honest effort at realism. It's not a PSA.
My intuition tells me that the intention here is to show how misguided homophobia is and how it not only is the source of great harm to others but also to oneself. In the right hands this could have been a brilliant movie, for example David Storey's.
