I haven't seen the movie and don't know if I will but, it is probably just a love story no matter who is loving who. I don't know how one becomes homosexual or heterosexual and I don't know if science will ever figure it out. I think it is just a case of what the individual brain finds attractive and pleasing. The same way some people are more attracted to blondes, brunettes, light skin, or dark skin. I can't tell you why I am more attracted to brown skin women than white women but I am (i'm a white guy). I think there is way to much focus on what is gay or strait. I don't believe there are more gays now than there were before, I think society is evoling to where more people can express there true feelings than before where they may have beaten, presecuted, institutionalised, or even killed for being who they are. Now this is just my opinion and you can take it or leave it.
