Yeah, the stupidity moments didn't quite reach Prometheus levels and some of the reactions (the ladies in the medbay to be exact) well well acted and spot on, BUT:
-The guy touching the pods (the other one at least stomped on it which was more realistic).
-The chick trusting a clearly disturbed android about being safe in a potentially monster infested necropolis and going to wash herself ALONE (when the most likely scenario is that she should be going through a mental breakdown after seen those creatures).
-The captain willingfully following David, who he just said he doesn't trust, into a dark room full of living eggs after he just explained to him he's been experimenting with the freaking monsters that killed half his crew (!)
Are friggin horrible and take the movie a whole notch down. I'm not professional scriptwriter and yet I could see several ways in which you can reach the same results without making your characters look like real morons. Seriously, is there no one proofreading for this stuff?
