1) Would you really go outside walking in an alien world without a weapon for a sci-expedition?
2) Would you just open your face shield without even checking if the outside world they just found is contaminated? Really?
3) How on earth David carries that big oozing vase into the ship without getting noticed?
4) When two people were out lost, without monitoring if there are any other threats to them Captain goes and sleep with a woman? Really? Wouldn't you keep atleast one of ur people to monitor the screens? And in the morning before you letting the other team go check what happened to them wouldn't they have system to replay and see what happened to those two without putting themselves in danger?
5)Would you really pet an unknown alien as if it's some kind of a pup? Really?
6) When that infected geologist returns to the ship, they opened the doors without even checking from their cameras. Really?
And the list goes on. Waste of my time.
