It says everything to me that in a year that also sees the release of films like The Hobbit, Avengers and the next Batman that this film is still by far and away the one i can't wait to see more than any other.
Always hoped we'd get a glimpse of what went on before Alien but never imagined it would end up with Ridley Scott doing another epic to tell us.
Also, debating if Alien or Aliens was the better film is pointless to me, both complete classics in their genres but that's it though, they are nothing alike except the fact they take place in the same universe.
