I have two big problems with this movie.
First, the only relationship I believed in was the one between Nate and Trent. There was real, palpable sexual and emotional attraction between those two, but there was none anywhere else in the movie. I didn't believe in Steven's relationship with Ray; every time he called him "Babe" I gave an involuntary shudder that he would say something like that to a stranger. Even worse, I didn't believe in anything at all between him and Nate, even conventional sibling affection, and the whole movie hangs on that supposedly overwhelming passion.
Second, the movie is based on a strange assumption that there's something so profoundly bad about sex between brothers that they have to sacrifice everything that matters to hide it and do everything they can to kill it. I never have understood that taboo. It's not like they'd have deformed babies. It's an absurd prohibition. But I suppose even now they wouldn't be able to get married, and since vicious lunatics have taken over the US government, that's not likely to get better anytime soon.
So I guess what I'm saying is that the actor who played Steven was badly miscast (he wasn't able to create any believable relationships on screen) and that the premise of the movie is absurd.
However, unlike many other reviewers, I loved the ending, for reasons that may be obvious from what I said earlier.
