Colored people in cages versus false flag, racial profiling, government propaganda bull shit. Tough...oh, the acting, story and such. Of course. Both well made and consistent. 24 gets the edge in entertainment. I'm definitely more likely to watch an episode of 24 whereas I'll never watch a single second of Oz again. Oz showed a whole generation some of what goes down in prison. That has some value, I guess. It also showed a range of prisoners rather than just stereotypes, so that is good too. I'd also give it the nod in acting and story.
Oz ftw.
