When I read that this was a movie set in a prison, I thought exactly that: it will be about an escape as usual. Then you explained that it's about a military prison, and that's something I haven't seen. The way you describe that it's a film about strategy and power, it really made me want to watch it.

I don't recognize the two main actors but I do recognize Mark Ruffalo, so there's another reason to not miss this movie. Thanks for your review!
