My problem with the Oscars is when some animated movie was up for Best Animated Film (which it won) and Best Movie categories a couple years ago. If that is the case, then they should have categories for best comedy, best action, best western (not the hotel), best sci-fi, best drama, etc. and any of those movies can be put up for Best Movie.
As for biggest sales, well, they have the peoples' choice awards... not that means as much as the Oscars.
