I don't really want to get into an argument with you, but since I haven't seen the film yet and I'm just going by what my friend told me, it doesn't present Oscar as a good person either and demonstrates his criminal acts and you don't always root for him in the movie. So I don't really see it as a white guilt film.
Anyway moving back to American Hustle, I still feel like Amy Adams will be pushed to supporting still to give her a higher chance of winning because the leading category is stacked this year. That might decrease Lawrence's chance for a nomination.
