I've never been to prison before but I think most of the basic stuff is accurate enough. Like the living conditions, activities that you are able to do, how they process you and the basis of how it's run and situations are handled. However, you are right in saying that tv producers play it up big, so as for the drama on the prison shows and movies I would say that they can and do happen, but not as often or as stacked as tv may portray it to be.
