I find the assumptions being drawn from a few snippets frankly depressing. Jumping space zombies? One tiny scene shows a man jumping from a vehicle - suddenly the whole film is about mutated Hills Have Eyes characters - really? Why would anyone draw these conclusions? There is evidence that a number of characters are suffering physically, beyond that everything remains speculation. Already people are writing it off - some because the alien isn't in - some because the jockey is 'assumed' to be too human. Boo to the detractors, if you can claim this isn't the film for you based on a short trailer your parameters for this prequel must have been very simplistic.
Well, as this level of fan boy hysteria isn't likely to end any time soon, I think the time has come to leave the Prometheus forum for those that want to throw tantrums and those that want to boast their assumed 'spoilers'.
To me, the trailer looks amazing. Whatever Ridley serves up will be a cut above the rest. I'm not expecting him to have lost his visual eye, his skill for implied violence and his european 'no punches pulled' attitude, and yes this does look epic. I've always liked Ridley Scott for his mix of movies but those that allow him to have complete control over the visuals - historical and Sci Fi are his best. I'll reserve judgement on how this affects A L I E N until June myself but right now I'm open to anything he wants to do with the expansion of what was, to a very large extent, his baby. If it's perverse and nasty, then this still looks like the bookend film that A L I E N always deserved but never got.
