That hallucination scene really got me though. I thought the guy had actually lived.
I knew it was a hallucination as soon as he showed up. Not only was it thematically obvious (having something happen right as a character is about to die/black out is usually a sure sign), but the depressurization would have killed her almost immediately, and as she said, there's no way he would've been able to get all the way back. It threw me off a bit when he knew something she didn't, but whatever.
Overall, yes, a very good movie. A nice realistic take on space, and a very thrilling and original concept.
