I think this post sums it up well. It really seems that the overall quality of films, including ones of color, have been really lacking. Most of the movies of color that I've seen advertised the past couple of years, seem to play on stereotypes. Big Momma's House, Norbit, Undercover Brother, and fill in the rest. There has to be better quality movies coming from the black community if they want to be considered Oscar material. Dream Girls is a perfect example of a movie that the black film makers should be making.
There is times where you wonder what the heck the Academy was thinking, like the time Morgan Freeman was overlooked for The Shaw shank Redemption. That entire movie was overlooked and it's a true classic in every sense of the word. It was almost a crime Morgan Freeman didn't win.
In fairness though, a lot of deserving films get overlooked and it has to do with the inside politics, movie promotion, and getting the attention of the Academy members with junkets and parties. This the stuff, we the public, never see. From all the buzz I've been reading, it looks like Dream girls is going to be a big winner. It's a great film and deserves everything it wins.
