As for them not knowing doesn't excuse them stepping out for the expedition.
They had suits to deal with an inhospitable stratosphere.
The stupidity starts when everyone brazenly takes their helmet off for the lulz.
But to step out of the security of the ship and jump onto the terrain of an unknown planet to an unknown architecture which belongs to an unknown intelligent lifeform?
Potentially risky exploration is how most of the world was discovered. There's a big jump from that to petting a hitherto undiscovered alien lifeform that's seemingly acting aggressively because you think it's cute. Especially
if your supposed to be an expert in fauna.
One is a hazard of the job, the other is going out of your way to be an idiot.
Yet the plain stupidity was the cinematic flair needed to propel the plot in this circumstance.
No, relying on characters making unrealistically
moronic decisions to propel the plot is simply bad plotting.Alien
managed to achieve what it wanted without ever inducing the audience to scream, "Why are you such a f*cking moron?!" at the screen.
It's not that they characters are dumb, it's that they're so
dumb I can't believe for even one moment that you'd spend millions, billions, trillions
on sending an expedition to the farthest reaches of known space to potentially make first contact with intelligent alien life, and then crew the ship with such a bunch of retards. It completely undermines the entire movie for me.
I mean, the crew of the Nostromo were exponentially smarter than these guys and they were just blue-collar truckers.
I always felt if you add in the deleted scenes they work better as characters since they provide at least a touch of justification for their actions.
This. Unfortunately by deleting all of those moments the scientists come across as utterly incompetent f*ckwits.
