Filming a stage play is a fool's game; you can't capture the power, intimacy and intensity of a great live show. Spike Lee played that fool's game and won. This is an amazing movie.
This is an exceptional feat by the writer, director, actor STU. Lee's lens is the perfect match for STU's fantastical, scary, and moving look at his own life story.
I like the music and writing a lot, but I have to admit that sometimes the acting seemed to overreach (even for theatre). I was actually not fond of Lee's direction- too many cuts, to many angles. Musicals come alive in long takes, and Lee's shot selection favored individual performances (which were telegraphed to the live audience, not the camera). There's enough humor and energy to make it worthwhile, though.
The genius of this is Stew but Lee does a great job of making this play seem vibrant and alive.
