Busta Rhymes as Rasaan

I did not care for Busta Rhymes portrayal as Rasaan with the non-stop cursing. Now I am not a prude but a competent actor would have been able to show his disdain to Shaft without every other word cursing! Great example is Jeffrey Wright characterization of Peoples Hernandez whom he made interesting with his cursing and insults. "Cornbread"? I will have to google that!
