I second this, with the exception of Alien 3.
Aliens (2) is my all-time personal favorite movie. It has no flaws, it's just action-packed perfection. How the hell can that be boring.
Alien 1 was kinda slow, but still a friggin classic.
Agreed. I didn't think 3 was very good, but not as bad as 4. Alien and Aliens are two of the best sci-fi films ever made, with Aliens being hands-down the best film James Cameron ever directed. Ridley Scott had Alien, but also some other greats (not the least of which was Blade Runner).
Maaaaaaaac!!! Get to da choppah!
Although his best cheese line from that movie was when he threw the knife at the guy, stuck him to a wall, and said, "steek around." Oh, Arnold, will your awkward accent ever get old?
