I really enjoyed the Frank Zappa documentary "Zappa". First, it was produced by the Zappa family and surprisingly showed Frank warts and all. I wish it would have explored more if there was a link between Frank's fascination with explosives as a child and his love of percussive instruments. Also, it might have delved more into the source of inspiration for some of the classics ("Peaches in Regalia" for instance). These are nit picks. Highly recommended.
