I don't really care about Alien all that much. I love the James Cameron sequel though.
You should meet Dave Kehr...
An empty-headed horror movie (1979) with nothing to recommend it beyond the disco-inspired art direction and some handsome, if gimmicky, cinematography. The science fiction trappings add little to the primitive conception, which features a rubber monster running amok in a spaceship. Director Ridley Scott relies on suspense techniques that looked tired in The Perils of Pauline: for the most part, things simply jump out and go "boo!" Under the circumstances, the allusions to Joseph Conrad (Nostromo) and Howard Hawks (The Thing) seem unforgivably presumptuous. Instead of characters, the film has bodies; some of them are lent by Sigourney Weaver, Tom Skerritt, Veronica Cartwright, and Yaphet Kotto."
