Bought the two-disc special editions of both Alien and Aliens two days ago. I suppose I could have held for eventually getting the Alien Quadrilogy, but that would have ment getting the 'interesting but not great' second and third sequels. With regards to the discs I actually bought, Twentieth Century Fox did a great job, at least judging from the presentation of these two genre classics. One can view them in either their theatrical or extended cuts, and there's some great featurettes too.
