I agree that Celebrity Pool can be very bad. In fact, both concepts have the potential to be very bad. Poor production values can kill any good concept. I would compare Celebrity Pool's concept to Bravo's Celebrity Poker. That show has incredibly badly played poker on it, but it gets ratings because it is entertaining...and some of those viewers will eventually turn into players.
I'm hopeful that both of these shows can hook in viewers that ESPN's coverage currently does not. That's not a shot at ESPN, but these shows are being created for different types of viewers.
In the end, more people viewing means more novice players, and more novice players eventually means more serious players.
