I know there's an existing thread, but I need to vent a little about a number of specific issues with the film. Please be aware spoilers follow.

How can we possibly care what happens to characters who are so incredibly stupid as to get to an alien world and take their helmets off? It's like we're watching science as performed in the world of idiocracy.

SCIENCE! YOU'RE DOING IT WRONG!

You discover that after taking off your helmet you have a parasite in your eye? Best thing to do is not tell anyone, let alone your wife, and join in with everyone taking their helmets off again. THAT'S SCIENCE!

As a biologist, you learn in biology science school that when discovering alien life, on an alien world, the best course of actions to pet it. SOMEONE ACED THEIR BIOLOGY SCIENCE SCHOOL EXAMS!

Let's not mention the agressive tentacle alien foetus which you just pulled out of your womb. We'll just leave that there because nothing bad could possibly happen if we do that.

Let's bring the old guy along, they'll never see that one coming.

Zombies. I really have no words.

It's midnight, I'm tired of writing about this fucking thing. There was so much potential here, but it was so disjointed and ridiculous that I can only be disappointed. Hoping for an expanded directors edition won't help explain why the film, like the characters, it's fatally infected with alien stupid.
