Speaking of prison movies, I have to say that The Shawshank Redemption, which occupies the first place in the history of modern movies, is the best movie in the history of movies, but at the beginning of its release, the box office was very bleak. This may be because later generations have a deeper understanding of this film and discovered the essence of the meaning of redemption. The whole film is about people adapting to the environment, not the environment adapting to people. This movie is the greatest movie, and friends who haven't seen it will not feel this classic movie immediately.
What I recommend to you is an action movie-life in prison, which reflects the prisoner's thinking and emotional mentality. Wade Porter (Stephen Dorff), the hero, was sentenced to prison for manslaughter, because he stopped the crime when he was ready to start his own business after he had a solid relationship with his wife and a healthy family and got a business loan. Facing the cruelty of reality, in order to integrate into this dirty environment as soon as possible and see his wife and children again, Wade joined the gang in prison, hoping to be released as soon as possible and see his wife and children again in this way.
