I quite enjoy the options of having different versions of films. Due to economics the requirements of theatrical and home video versions are quite different. For theatrical showings films have to often come in under a certain length (I think to get his R-rating Scott had to make compromises in terms of running time) and often they get edited for rating and censorship, things which aren't an issue on home video. Of course many directors cuts are redundant fiddling around, but that's fine if the original is also present, which it always almost is (and Star Wars fans are suckers anyway
). I'll never understand the complaints over having more options rather than less.
