There's some pretty big names involved in the story and the script - Annie Proulx and Larry McMurtry. I'd expect it to be controversial, but I'll bet it's a good flick. Here's the blurb from allmovie.com:

Ang Lee's adaptation of E. Annie Proulx's story Brokeback Mountain stars Jake Gyllenhaal and Heath Ledger as young cowboys named Jack Twist and Ennis Del Mar. Each of them is hired to work cattle on the title location and they soon bond very closely. Their platonic relationship explodes into a physical one, but eventually the two are separated when their job comes to an end. Although the two follow different life paths -- one becoming a father of two and the other becoming a business success -- they have a reunion years later. Each is affected profoundly by the rekindling of their old feelings for each other. Those feelings lead each to consider what continuing their hidden relationship would cost them. The screenplay was written by Pulitzer Prize-winning author Larry McMurtry and Diana Ossana. -- Perry Seibert
