That's true. I am well prepared for most things. But then I have a trapdoor to Hell in my hallway, several friends in literally low places down there, and I know where all the vampires live (Purley, if you've been to the Wetherspoons you'll know where they got the idea for the Titty Twister bar in From Dusk till Dawn, well, if the vampires were more suburban which they mostly are).
But yes, it's not just the stupid, it's the doing things for no good reason. I'm taking my helmet off because the plot says I should. There's no reason for it, there's no motivation. There's lots of reasons why you shouldn't. I mean, seriously, Prince could come back from the dead and do a free concert in the Hollywood Bowl, and there's more reasons for not taking your fucking helmet off on an alien world than their would be audience queuing. I mean seriously at least think of an excuse. Maybe have your character trip up and smash his helmet, have an air supply fault, have the spores eat through the suit seals, some contrivance that isn't just stupid. It's full of shit like that. It's a bit like Dan Brown to be honest, were the characters run around for no other reason than the plot tells them too. They have no agency of their own. It's just sloppy and it annoys me because they're taking the piss. If a character ever escapes from a Dan Brown book the first thing they'd do would do would be murder Dan Brown with a copy of one of his own books. Sophia Langoustine, the athletically blonde art dealer, loomed silhouetted over Brown, the writer of over ten books including the bestselling Da Vinci Code. She grinned a wicked smile on her face as she forced a copy of the oversized tome down his choking throat.
"That's for making run around Europe with some halfwit as nothing other than a dumb plot cypher in your stupid books,"
she said coldly with her blue eyes.
Same in Prometheus. The crew are supposed to be scientists. Having travelled across the galaxy, two of them immediately want to go back to the ship because they're scared of the dark. Then they get lost for no reason at all. And then they're tickling a weird penis alien because that's not scary at all. I run away from giant penises. Even if they're not alien. Then they turned into monsters. All just because.
It's probably a good thing I didn't notice James Cameron and Sigourney Weaver walk past me the other month. We'd still be having this conversation. Or as they'd likely call it, a 'hostage situation.'
