Like TB says, its all the customers's fault.
If the movie customer is willing to put up with crap, then that's all he deserves. No one puts a gun to their head and makes them buy a ticket.
As for the artists and technicians whose hard work and talent is wasted on producing crap, well, they're just employees. If they don't like it, they can always choose some other profession.
Neither the consumers who buy the product, nor the workers who make it should have any say in this. Its the job creators that take the risks who have the right to call the shots.
