Do NOT watch the trailer. It basically gives away some of the best parts of the film and would spoil their impact.

It was darker than I expected, but in a good way. Great cast all round, especially Carla Gugino, and a really well-paced, well thought out story. I haven't read any negative reviews on here but I am surprised it's not higher rated on IMDB. Might have contributed to why I waited so long to watch it, and I wish I hadn't.

Remarkably similar to 127 hours. Even the escape is just as gruesome, so if you're squeamish be prepared to look away.

It's a happy / satisfying ending thank goodness, which I wasn't really expecting but was very grateful for.

I only wish there hadn't been so many flashbacks. I would have preferred more real time storytelling from Jess to keep the audience focussed in the room. And the eclipse thing was a bit overdone.
