This was much better than the usual pulpy, cheap action movie, with their fantastic and improbably stunts and gimmicks. I tells a true life story in a mostly accurate way, with only a bit of artistic license for dramatic purposes. It was realistic and the characters were all fleshed out and believable, I enjoyed it, and was pretty absorbed as I watched it, with almost no pausing or flipping, and I thought about it a lot afterwards and rewatched it almost immediately to get more out of it, which I would never do with the usual generic trashy franchise movie.
Highly recommend it for watching alone or with friends, if you're all in the mood for something a bit more serious and life like.
