Sorry I just have to comment on the irony of it all.
Rabid Alien fans frothing at the mouth dismissing Predator with one sentance , then right underneath the "Prometheus won't be Alien" thread.
Um, I'm not sure what you mean by this. The title of this thread is referring to the fact that Prometheus isn't going to follow the same structure as Alien, whilst still being set in the same universe. What's any of this got to do with Predator?!
Because if Prometheus turns out to be a steaming pile of shizen and totally changes everything Alien fans ever debated over the past 30 years, you'll all be the first to punt it into a separate stand alone franchise, claiming "that's not how it happened" or it's "loosely based"
If one thing's certain about this site, it's that a lot of fans choose their own canon, even when it's officially so.
They might not be correct, but people can dream up what they like, it's part of this whole website. I for one don't mesh any together, I respect or disrespect each franchise separately. .
