Oh, Ridley Scott. We had such high hopes for your Alien prequel movie Prometheus, but poor choices made it a funhouse of ridiculous and horribly distracting violations of science -- and common sense. Untold light-years from Earth, an android can't properly count time; when asked how long the mission has lasted, he says, "2 years, 4 months, 18 days, 36 hours, 15 minutes," not "2 years, 4 months, 19 days, 12 hours and 15 minutes". What's more, a crew awakens from hibernation pods having never met one another -- on perhaps the most resource-intensive and expensive endeavor humanity has ever attempted. It only gets worse when scientists and mercenaries hop off the spaceship and enter an alien temple. We witness some of "the most irresponsible, inept archaeologists ever to don spacesuits," as our Twitter follower Rob Hinchcliffe put it, take off their helmets just minutes after leaving the spacecraft. Advanced atmospheric sensors or not, this is a terrible idea. What if there's an unknown, undetectable, and highly toxic compound in the air? Or a virulent strain of life? No matter: Soon enough the movie's characters are touching creepy-looking aliens (and, of course, dying horrible deaths). Then they carry alien heads inside their spaceship and electrocute them until they explode. And then, only after all of this death and catastrophe, they decide to map the temple. Just about the only thing that Scott got right with Prometheus was the organizational ineptitude of the mission, which was essentially a doomed-to-catastrophically-fail season of Big Brother on an alien world. Scientific violation index: Maddening P.S. Our favorite confrontation of plot holes, scientific conundrums, and abuse of common sense is this comedic, question-filled video by Red Letter Media.
