Actually, pretty good.. I usually hold so much disdain for all Hollywood movie portrayals, whether they be jazz, doo-wop, rhythm and blues.. I always find them so over the top, ridiculous, more than often inaccurate both chronologically and factually. I thought Bird and Round Midnight were quite disappointing, but this montage of the life of Miles Davis was done artistically well. It's not a biography in the traditional sense with a beginning, a middle, and an ending, but rather selected incidents from the trumpeter's life with flashbacks-- a montage, as it were. Excellent performances, particularly by Cheadle, and especially impressive was the fact that Mr. Cheadle took the time to learn the actual trumpet fingerings and give true realism to this work, as a special treat to the trumpeters in the audience. Worth seeing a least once, maybe twice...
