So many movies that come out on DVD these days have a "director's cut" that comes out a few months later. I mean, it was cool for the LOTR Trilogy, since there were significant additions to the story, but these days, even titles like Daredevil, Wild Things, XxX and Not Another Teen Movie get extended/director's cuts. These sometimes contain less than 5 minutes of additional useless footage - just to get people to double dip due to an "unrated" tag on the label.
Does anyone know of a site that compares original releases with extended/unrated/director's cut versions, listing scenes that were added/altered? To help consumers decide if the "extended cut" actually makes it worth purchasing the same title twice.
