Why does David infect Holloway?
Why does Dr Retard Mcspazzoid try to touch the alien snake in the space tomb already described BY HIM as "something out of a Holocaust painting"?
Why does everyone completely ignore the fact that their ship was just attacked by the mutated remains of a former team-mate, forgetting his brutal rampage that killed several crewmembers in literally five seconds?
Why does the female protaganist forget about her husband's agonising flaming death in the time it takes to change scene?
Why did neither the female protaganist or her Ayran counterpart think to run sideways when being chased by the alien doughnought of doom?
Prometheus was a watchable film, but not even an oddly dolphin shaped Xenomorph can stop me from asking so many questions.
Why does David Infect Holloway? The film doesn't give a direct answer. I think it was just to see what would happen - he is curious after all, and Weyland asked him to "try harder" in the quest to find something, ANYTHING that would keep him alive. He also clearly dislikes Holloway, despite the film telling us that he can't feel emotions.
Why does the biologist touch the snake thing? Because he's an idiot, I guess? Yeah, there is no real excuse for this, other than "dumb-character is dumb" - but if he was that dumb, surely he couldn't have been allowed on this mission!
Why do people forget the rampage? Uhhh.....ohh... well.... hm. Yeah. Weird, huh?
Why does Shaw forget about Charlie's agonizing flamethrower induced death? Uh... shock? That's the best excuse I could come up with.
Why didn't they think to run sideways? Well.... the script says that they didn't think to run sideways? Is.. that.. a proper reason? Please?
Yeeeaaaah. Film's got pacing and plot problems. Not surprising given the writer.... was one of the co-creators and writers of LOST.
