There are some, not me, who would undercut Alien, calling it a "Haunted House in space". I think it makes a point; thematicaly its nothing new. Still, it's the pinacle of the genre, if it infact belongs in the genre. Aliens isn't better or worse, its completely different. The film employs very different kinds of tension. I really enjoyed the part where there were cornered in the room, with the sentinel guns blasting (directors cut only), and then when they came in through the cieling. I liked the role of brock (or whatever the company man's name was). Newt makes better sense in the directors cut, it fleshes out the mother-daughter relationship between her and Ripley more. I think I could have done with more Deception and deciet from Weiland-Yutai (though, if i had my way, the alien franchise would run like a 5 hour conspiracy theory/law and order detailing the company's exploits).
What sucks is Alien Resurection. worst Sequal Evar. And to think that the people responsible for it claimed to make it as an apology for everybody who went to see Alien 3, and didn't like it becuase it "wasn't enough like Aliens, plus Ripley killed herself in the end, which was gay".
Worst sequals list:
Alien Resurection
Rocky V
Scream 2,3
Godfather 3
Starwars 1,2,6, and probably 3
Startrek (take your pick. Somebody dressed as a klingon should stand by the box office and poke you in the eye when you buy your ticket, just to hammer the point home that this wasn't the best use of $7.50)
Red Dragon and Hanibal - manhunter was so much better, there was no saving that other damned movie. Though I did enjoy the Comedia del Arte scene in Florence.
Batman and Robin - If given the choice between seeing 8 hours of holocaust footage, or 5 minutes of george cloony invading Mr. Freeze's secret ice cream factory lair, i'd hesitate, then ask for the nazi highlight reel.
