I'm friends with someone who never saw the
Alien films, and thought
Prometheus looked terrible. He did end up seeing the movie (before I did, actually), and found it to be interesting, but not great by any means; it did, however, intrigue him enough to watch
Alien (I'm not sure if he watched the sequels, but I know he saw the first one). Only after discussing the film with me and reading some articles online (particularly this one:
http://cavalorn.livejournal.com/584135.html#cutid1) did he grow to really love the film.
When I went to see
Prometheus last Wednesday with some other friends, I loved it, as did a friend who saw
Alien with me a while ago (though if I recall, he found
Alien kind of boring). Another friend who just saw
Alien with me recently, and part of
Aliens on his own, also really liked
Prometheus from what I could tell. I let him borrow
Aliens and
AlienĀ³ a while ago, waiting to hear back about those. A third friend who I saw it with said he understands why people felt let down by the film. I'm not sure if he has ever seen
Alien, though.
