The promise of cable TV has not been kept. It is now for the most part nothing but trash. No matter how many Discovery and Military shows are out there, the truth is most content is aimed at people educated to an eighth grade level or less.
Even the The History Channel, once my favorite during its Hitler Channel origins, is now just a repository for hours and hours of re-runs of Pawn Stars, Ancient Aliens, UFO Stories, and American Pickers and other second-rate shows meant to pad out the time between their rare presentation of an actual historical show.
The good stuff is at the BBC, and other documentaries.
The purpose of most reality TV is to denigrate people and knock them into the dirt, that is, everyone except the final 'winner', who proudly stands on the corpses of the people they managed to somehow out-last, people who they formerly called 'team-mates.'
I watched the Hustlers last night for the first time, and did not see anything to recommend it except some pretty good pool shooting by a girl and by a double-amputee. Even Mike Dechaine didn't show much skill, though he won last night's competition. I think they could make the show a success by stressing the pool shots, the technique, and the skill needed to pull off shots and shape. In other words, a pool instruction show disguised as reality TV. But I doubt that is the way they will go - I think they will follow the usual reality format where one person has to verbally and mentally and without ethics nearly destroy every other person, just to be announced as 'the winner'.
