I think I'll hold off for post-release reviews, though this trailer and another trailer-ish video piqued my interest:
http://www.imdb.com/video/imdb/vi2390728985/Alien is a great movie. Aliens took some of what was good from Alien and made a pretty damn good action movie. Is it intended for Prometheus to be compared to either of these two, or is it going to be just another movie in the set? Is it going to do something new and interesting, or be merely on par with say Alien3?
I'll give it the benefit of the doubt that it won't S*** as much as say Alien Resurrection or AvP. I don't really want to see something on par with Alien3 unless I'm bored at some point.
I don't know what you all think, but that's my feeling on the topic.
