Earlier today, Some Dude On Twitter™ Who Works For Variety™ (This Guy, if you're interested in precisely what bridge I'm in the process of napalming) tweeted "If Ridley Scott's cat ate the scripts of Alien & Blade Runner, then coughed them up as a hairball, that would be the script of Prometheus." Ha ha ha ha ha, wow, you're so hilarious, how can I ever get to be as funny as you? Dipshit. No seriously.
You, mon sembable, mon frere, will likely read a lot more bitching about the script of Prometheus. I even did a little myself. But the point of it is, it's not a "hairball" merely of Alien and Blade Runner, it's EVERY SCIENCE FICTION MOVIE EVER MADE. When Worlds Collide, The Thing From Another World, 2001: A Space Odyssey, that weird Corman thing with Joanie from Happy Days, and more, and more, and more; they are all in there. Some may find this annoying, but I was kind of delighted, and it really did not detract from the film's "sincere" effects for the most part, so, again, ha ha ha ha ha with the hairball and all.
