Some of the best brains of humanity and not one of them can make a single logical decision. Let's take our helmets off, ok, you 2 just wander off, it's cool. Oh dear, they're lost in tunnels, we won't use the ground penetrating radar we have because that's needed for the alien ship reveal scene near the end. Lets pet the alien snake, because that's what a zoologist would do on alien planet. Lets take this alien head back to the ship, and stick some electrodes in it, **** using any kind of quarantine. Oh dear, one of us is sick, we didn't bother bringing anything to help him. We have a flame thrower though, because it was in the first movie, no other weapons with which to defend ourselves. Oh, I'm pregnant, better have a quick abortion and then do soem running around. oh look, my alien baby is now a few minutes old and become the size of a small whale, it must've eaten a lot, oh look, it's eaten absolutely **** all.
**** off.

This reads like gogglebox for angry people
