I just saw this Dalton Ross glutton column about the inability to resist buying a DVD. We've all been there. The trick is remembering the difference between two key, sometimes but not always overlapping criteria. There are movies that are great. We love them. We make lists of them. We respect them. But we don't often have the impulse to sit down and watch them again all the way through. And then there is that key "watchability" standard. The first category will always be there just a Netflix queue slot away. That's for "Paths of Glory," "The Grapes of Wrath," "The Magnificent Ambersons," and the Criterion edition of just about anything. That "to own" category is for movies you want to watch when you have the flu. I'm thinking "Galaxy Quest," "Happy Texas," "The Tao of Steve," "Men in Black," "Get Shorty," "Duck Soup," and, of course, "Weekend at Bernie's." Everything else...just think "catch and release."
