I totally buy this data driven observation, and I'm not even completely opposed to it, save for sucker bets like this Bebop adaptation, because it's not like it was all pure artistic endeavor previously. The big problem being the worst of human nature and error still tainting the execution, first on the executive level as always, and because while everything has a polished "prestige tv" veneer now, and this gives tremendous opportunity to heretofore underrepresented actors, creators and audiences, there's only so many people with the combination of talent, training and experience out there right now to actually produce a really good show. So, until some of these new creatives and crew people get the reps, there's going to continue to be a dilution of quality (they're going to have to start recruiting career waiters to be actors =) and a lot of otherwise mediocre shit passing through, but at least there's potentially a light at the end of the tunnel (that may or may not be a train).
