Personally, I think I can overwatch it. I missed it in the cinema (actually, it's still running over here, but I hate subtitling, and also, I'm afraid to make a fool of myself blubbering away in public...). Got the DVD, and saw that 7 times in the first 3 weeks. Then I watched seperate scenes while working on my own edition of the screenplay (yes, I found other ways to deal with my obsession...). Eventually, three weeks on, I rewatched the entire film an 8th time, and while I was still very moved, noticed that it didn't quite hit me like a ton of bricks the way it did before. So I have now decided not to watch it for several months, at the least.
... But I do reread the story, as well as the rest of "Close Range", peruse Avedon's "In the American West", listen to the soundtrack (and to Charlie Haden & Pat Metheny's "Beyond the Missouri Sky"), got the DVD of "The last Picture Show", ordered a book of Wyoming landscape photography, not to mention the fact I'm hanging around boards like these on a daily basis... you get the picture. I suppose I can hardly pretend to have quit BBM.
