I wish I could understand what Ennis and Jack were talking about in the film...(good to know C didn't understand them totally either)
I wish I were a better reviewer, but I'm not, so I quote this from The Guardian:
'Brokeback Mountain is the story of how most of our lives, gay and straight, are defined by one moment in which things go gloriously and naturally right, when everything falls into place, but which is then infected by the bacilli of wrongness. Ennis and Jack, flawed as they are, do their best to resist the encroachment of that infection; they fight not just against bigotry, but dullness and mediocrity. Their story is not tragic, but heroic.' (click me to read the whole review)
Well, try not to dislike the metaphors used in that quote: 'the bacilli of wrongness' and 'the encroachment of that infection'. Being in love can feel like illness at times. Oh, well, this film, to me, is about suppression; the pain is there, because they compromise. Not all could happily love, though.
I can't quite tell why they love each other tho. But, love is beyond reason, uh?!
This film also gives the audience a chance to rethink about whom they truly love. They probably all cried because they suddenly realised they long lost the ability to love like Ennis and Jack in the film, or because their old wounds fiercely throbbed again, never healed, probably never ever will.
Excellent acting and gorgeous scenery...
