I really enjoyed the film, and implore more people to justify their opinions, rather than just saying 'it sux0r'd'...
Essentially, it was a criticism of the time and place in which the two leads lived. People were small minded, ingnorant, simple. You were expected to be a certain type of person, and to stray from the line was often not acceptable, especially to stray in a homosexual direction.
Heath Ledger was the stoic, repressed, most tormented of the two leads. He was far more in denial than Jake's character, far more troubled by the prospect of being gay, and the implication that would hold for his future, were people to discover it.
Jake Gyllenhall was the bouncy, expressive, more open of the two. He certainly wasn't comfortable with being gay, but he was far more open to it that Heath, far more willing to consider a future for the two of them that went beyond biannual fishing trips.
The story was totally tragic, by portraying the decline in the two lives and the detremental effects their denial had on others through time, Ang Lee has really demonstrated how destructive a force denial can be. But more than that, it is strongly suggested that their only way forward in such a world was to act heterosexual, start a family, do what's expected of them. Therefore we totally sympathise with both characters, because we understand they really didn't have a choice...The story of the gay couple who were severely punished for trying to live together sums this feeling up perfectly.
Some people found the sexual acts too carnal, i think it needs to be understood that both characters were experiencing something they hardly understood, they found their situation to be ineffable and very confusing. They are rough with each other mainly because they are both fighting their urges, themselves, and each other and because they are very uncertain and unfamilar with the territory.
My only major critism, is as someone above identified, i think the relationship could have been fleshed out fruther, we never truely understand what they love about each other so much. I didn't think it was totally undeveloped, but as this is a tragic love story, it could have used some more telling dialogue.
Anyway...I should take a part-time course in film studies maybe
I myself totally empathized with the characters, as i am i bisexual, who for a number of justifyable reasons decided to deny his sexuality. I suffered enormously in the long run, with countless psychological problems resulting from this decision. Sometimes cultural, psychological, and situational factors combine to result in denial of sexuality. i totally relate, GREAT FILM!
PS...i think some of the people who criticise it are being just as homophobic, small minded and ignorant as the type of people the film essentially exists to criticise! PUT THAT IN YOUR PIPE AND SMOKE IT!
