I know the other films are going to look amazing and have interesting extras.
But personally for me, I can't wait to see what they did with Alien 3 the extended version. In the special edition DVD you can clearly tell the delete footage was poorly colour graded with the original version. The sound was kind of distored at times too.
Hopefully they fixed it all up and it all matches perfectly, that would be insane, that will be like watching Alien 3 for the first time.
