I'll take movies winning that no one saw over the "Academy Awards" turning into the Grammys. If you want that then most of the other movie awards are for you (which I realize is partly what you are saying).
I'm not saying it has to go to whoever sold the most tickets, but why not remove all the bias and judge simply on the dimensions of the film itself. I guess there is some risk that whichever movie sells the most tickets also ends up getting the award, but selling a boatload of tickets is generally an early indicator that the movie is pretty good.
Because it will never happen. And wow do I not agree with you "boatload of tickets generally" means it's good theory.
