It was a pointless movie where the main character behaves illogically and irrationally despite being a scientist. I kept watching the movie waiting for there to be a point. By the time she killed herself it was just annoying. It solved nothing, wasted the other characters time (Which he didn't have a lot of if he wanted to escape), prooved nothing and was no pointless. Also why the hell was she wearing shorts with a coat half the time? She can cobble together an oxygen suit but not a few pairs of pants?
