A thread for one of the best sci-fi/horror series ever.

I'm a massive Alien series fan. I love anything and everything to with the series, even Alien 3 (well, the director's release anyway). If Sigourney asked me to be her personal slave on the next alien movie set in a pink tutu and rollerblades I would. For her. Maybe

Interesting side note: Aliens is rated "PG-12+" in Japan

Who else is a fan? Does anyone else have the quadrilogy 9 dvd set with its completely orgasmic special features and production material? What parts are you favourites, what would you change if you could? Are you hoping for a 5th movie?
