Cracker, it seems like you really like Prometheus. But you're getting upset for no reason buddy.
I suspend disbelief all the time. But we suspend disbelief in our own ways. Usually for me, once the world is established, then based on that frame of reference, the more things that make sense, the better the film for me. I'm willing to believe that technology has advanced enough for the cryo stuff to work. I'm willing to believe that the atmosphere inside the ship resembles that of earth. I'm willing to believe a lot. But in a weird way, I need other things to make sense. If I feel that they cheated a bit too much in this movie, I don't see why that should be upsetting. Scott is a great filmmaker. So is his brother. But I still feel like he could have done a bit more on this one.
cheers
