In anticipation of Prometheus being crowned the best of all time, I thought I'd get this thread in before it's released.
I'm not really up on Sci-Fi films from the 50's and 60's etc... so the poll will be heavily skewed in favour of films from the last 35 years. With the odd old classic I've seen thrown in. If your favourite isn't in the poll, select other.
It's also hard to classify what is a Sci-Fi film, but I think a case can be made for all on the poll to qualify. Poll to follow.
