okay, here are what i don't think this movie and its screenplay are good enough: 1) never thought the black prisoners and the white ones could be so united in any prison history 2) the leader of the white prisoner, and the leader of the black ones seemed to respect each other quite well, they also cooperated with each other like brothers. the movie was released in 1969, and probably shot in the year before. do you think in that era and time frame, the blacks could have mixed with the whites so smoothly? they were used to be oil and water, they never could be mixed together, no matter what. 3) the black guy got a thick and high quality cow hide belt, and when he wanted to punch somebody, he just unbelted it from his waist and wrapped around his right fist. are you sure, dude? prisoners could have regular belts around his waists and never considered a dangerous weapon to other inmates and the prisons authorities? if shanks made in plastic or metal are considered deadly weapons, what about the belts? they could also be used as deadly weapons, don't you think? there are so many details that didn't feel all right but you can also let them go if you really need to watch a not quite exciting prison riot film but either a black prisoner's day dream or fantasy.
