Outrunning a falling ship

I quite enjoyed this film...Until Shaw and Vickers tried to outrun the falling engineer ship. The ship is falling towards them, they can either try to run in a straight line following the longest section of the ship out, or they could run a few metres to their right. They opt to run forwards, presumably because they are complete idiots, when Shaw falls down, she rolls to the right and that roll is enough to get her out of the way. Vickers continues to run forwards and gets crushed by the ship. Running a few metres to her right just never entered her head. Ironically, the film is available in 3D, but the characters brains appear to only work in two dimentions. That part was so stupid, so ridiculous and so horrible that it ruined the entire film for me.
