A subtle but very satisfying horror

Wow, this really worked for me. The horror elements are subtle and tasteful, the evolving mystery is enticing and the element of grief is mixed in well. But mostly, I was quite stunned with the lead actress, who totally nails it and makes everything work beautifully.

Moody and dark

This horror is carried almost exclusively on atmosphere, darkness, a deep sense of desolation and fear within. It is done wonderfully, it looks very moody and is acted well. At around 3 quarters through I felt a slight yearning for some twist or acceleration, but perhaps it is best without it.

Good, misses some opportunities

A more than decent survival and motherhood story, but it could have been denser and nerve-wrecking in places. Also, there's a twist near the end that could have been huge, but it's almost like they didn't really follow up on it, and went with a rather swampy emotional ending instead.

Yes it's good (But not that good)

Finally I saw this endlessly lauded movie. I agree that it is good and very gripping. I can't remember a recent movie that I was this much 'into'. But the best movie ever made? Perhaps I am just not that into prison movies, and the idea that only super smart will make it is hardly inspiring, is it?

A nice tale that had slightly more potential

It's a sympathetic tale of human friendship and it works for the most part, growing on me as it went on. However, I think the robot's progress in learning, behavior and humor could have been more subtle, interesting and refined, and making him sound like Borat was part of the problem.
