I like many of you here and firmly stationed in the YES camp. But I have friends that think watching a movie more than once is stupid, and thus buying a DVD/video is a waste of money. I can sit and watch a favourite flicck 3 or 4 times in one day (not often mind you :b). But thinking about it, I can't come up with many reasons why rewatching is a good idea. 1) Your understanding of films with twist endings often benefits from repeat viewings. See Usual Suspects, Fight Club etc.... 2) Like 1), you only get everything out of films with a lot of details after multiple viewings. No one could claim to have spotted/appreciated all the symolism a director has incorporated into a movie. See Amelie, Out of Sight and so many others I couldnt even begin to list them.... 3) For sheer entertainment value - there are some films, especially comedies, that get better the more you watch them. Each time I watch Being John Malkovich, its funnier than the previous time! Any others?
