How so? Everything I've heard has said he's a good writer and has a good voice for it. Haven't read any of it myself though.
It is a bit tough to read not because of his writing, but because he writes about his favorite TV shows, musicians, and other events surrounding his childhood and much of it is kind of obscure to Americans - especially our age group. I had to Google a lot of the stuff which slows up my reading pace.
Edit: Forgot to mention there's no chapters or pauses within the writing. You kind of just have to take breaks when you see fit.
