Why "Confessions of a Conjuror" is a Brilliant Autobiography

I'm just finishing Derren Brown's "Confessions of a Conjuror" (finally), an autobiography with an unusually high quantity of footnotes and tangential ramblings. Plenty of readers have criticized the book for these features, but I actually think it is quite good.

Through his rambling writing style, Derren has provided what no other biographer could possibly provide -- a look inside of his mind as it operates on a daily basis. He writes about unusual thoughts that no one else writes about (witness, ege, his lengthy analysis of the awkwardness of seeing someone start to get off an elevator at the wrong floor). But it all serves a purpose.
