A solid biography, though I don't have anything in particular to say about it. It throws in all the classic anecdotes and quotes you expect (which are more than worth their weight in gold - certainly, the price of admission) doesn't try to whitewash Feynman despite the temptation to hero-worship, and includes some critical examination, does at least try to explain all the physics which earned Feynman his prestige, etc. It's a well-regarded widely-read biography on an excellent subject which I have nothing to say against.
