Finally broke down and watched this On Demand. Overall, it was better than I feared it would be, which may be damning with faint praise.
Although what the Jim character was wrong, wrong wrong ... at the same time, I was wondering what I'd do if I was in his place. I'd like to think I'd be noble and self-sacrificing and all that, but to spend 50 or 60 years alone — and with a handy (albeit disgusting) solution to the problem so close at hand — I can't say I wouldn't be severely tempted to follow his course of action.
As for Aurora, I thought the movie did a great job at showing her anger at what happened (few actors do pissed off as well as Lawrence), but short-changed her journey to forgiveness. Like a poster said above, the third act seemed awfully rushed.
Overall, a decent, but not great, movie.
