Hard to believe anybody, even Ed Champion, could get so worked up over one movie being awarded an Oscar at the expense of another. An Oscar may boost a film's fortunes, or the fortunes of its star/director/writer/etc, but as an indicator of a movie's artistic success it's up there with box office figures and the opinion of that blog-hating guy who writes that blog for l'Age.
Anyway, if you want an Oscar injustice, how about The Godfather Pt. II winning Best Picture in 1974. It's Alive wuz robbed!
