Stupidity: To face his very human boss in the movie finale, Don pulls a gun from his coat, a gun that somehow he did not deem necessary to carry around when they were hunting dangerous brainsucking aliens, arming himself with blunt instruments instead. (01:11:25)

Stupidity: Mike's motivations lack any plausibility. He sabotages the depressurization process because he does not want the creatures sucked away, but rather sell them to laboratories. Greed is his sole motive, but (besides the fact that he can easily sell the dead ones as he originally planned) he is willing to blow himself up with the plane lighting a dynamite stick (?), only because he really wanted to make a few extra bucks and wasn't happy with insurance money and the millions promised by the girl.

Stupidity: If there was a live camera feed right where the eggs were, one wonders how everyone missed the 'small' fact that they hatched. That of course combined with the fact that going for no reason in the nest of the creatures that nearly killed another crewmember is suicidal, and Bob goes with no weapons and with one small plastic fruit crate to fetch eggs that are bigger than an ostrich's.
