I give it a 10 out of 10 because it kept me in front of the screen, I think it portrayed the prison life from many different perspectives. Despite this dark storyline it's a film I enjoyed more than many others in the last years. It's the first time I leave a comment in 3 years at IMDb, just to let you understand how I enjoyed this film. All characters are developed to suit the overall story, without going too deep or to shallow. Especially Harold Perrineau surprised me, this is his best performance to date. Val Kilmer was just a pleasure to see, this dark Character suited him very well, his acting becomes better and better the older he gets. Great screenplay followed up by a formidable cast. I look forward to see more from Ric Roman Waugh.
