I randomly stumbled onto this movie and was intrigued because it had the King Slayer and the Punisher in a prison crime drama. Seeing Jamie Lannister in Aryan brotherhood prison tats had me intrigued.
I thought it was going to be a corny low budget gangster flick with a title like Shot Caller but it was actually quite good. It's basically about an upper middle-class white collar guy who goes to prison and ends up joining a gang in order to survive, then does gangster shit when he's out. It's social commentary about the prison institution and how it doesn't help anybody but it doesn't shove that message down your throat. Interesting story and good performances by everybody involved, especially by Nikolaj Coster-Waldau.
One of the better movies I've seen this year. Highly recommend it.
