Science fiction fans
Science fiction fans are easily the worst out there. I prefer Adam Sandler fans.
When you see a movie about space with mentions of "Icarus" and themes of religion, why would you start expecting 100% scientific fact? Movies are made by artists, not scientists. This is not just with this movie, but in general.
Reading the boards of BSG, Lost, Gravity, etc. I almost feel bad for these people. Then I realize that they are the reason we rarely get quality TV in America. It either has to be perfect fact, or we have to destroy it. There is no license for story telling. We'd rather see Big Brother Season 454.
