Creativity vacuum in Hollywood

Maybe it's just taken me awhile to notice, but it seems the decision-makers in the traditional movie industry have lost interest and drive to develop fresh, new movie concepts.
The one notable exception appears in the animation arena - no overt duplication of ideas there.
I'm just growing weary of modern remakes of old movies.Normally, I try not to complain without having a solution. I do have a suggestion - that the major film studios develop teams, to include regular old Joes and Marys, to develop new ideas. Sure, someone would need to get creativity and writing credit, but if you have a "thinktank" generating fresh concepts, more people might actually show up to watch movies.
I don't have any ideas for a script myself. If I do, I think it needs to become a book first. :)
