I started thinking about this yesterday. It seems like the writers purposefully do not favor any one character. They introduce characters two at a time and often kill off characters or write them off. Just when the focus is on one character they will ignore them in the next episode. This is pretty unique even compared to breakthru shows like 24, Sopranos, etc. I guess you could argue that Oz itself is the main character or "the system" is the main character but this is incorrect- it is merely a setting- although it does have its own personality and at sometimes feels "alive" it is all in our imagination because Oz is just metal and concrete... Which leads me back to my original question: Who is the main character? Or if you don't want to answer that tell me who you think gets the most screen time or who you think the writers favor the most.
Thanks for your input!
