One of the Best!
This movie will always be a classic. In fact, contrary to popular belief, at heart this is not even a science fiction movie: it is actually one of the better horror movies ever made. It's like "The Shining " meets "10 Little Indians" in space. The Director's Cut adds little to the overall experience of the story - I only noticed three key scenes that added/changed your understanding the story ever so slightly. But, if you are a big fan of the movie, it is always fun to be able to see around a few more corners than you had been able to before. I recommend this movie if for no other reason than to immerse yourself in a truly great horror classic on the big screen - just be sure to look away multiple times, not from the alien, but from the cheesy spaceship. Now there's something the director should have cut.
