It's sort of a well-known pitfall of centralized product management. In the short term, it's less risky and more profitable to create a product that 1000 people would find passable, than to create 10 different products that would be loved by their 100-people audiences and ignored otherwise. However, in the long term this erodes people's expectations of future products and they eventually move on. That's a part of the normal economic cycle and the reason why big corporations eventually go bust.

I think, this process is happening throughout the entire motion picture industry and in the next 10-20 years we will likely see a shift to some new type of entertainment that hasn't been ruined by formalized best practices yet.
