"Great book ruined by unimaginably awful reading"
It is difficult to say I enjoyed this book when I could barely stomach the awful narration by Scott Brick. I think having him narrate this (as well as all the other Michael Pollan books) is a huge disservice to MP fans. I think having my eyes poked out would be preferable to listening to another book by this reader, even if it were my most favourite book ever.
The sing-songy and overly dramatic (in random places that have nothing to do with the storyline) reading completely take away any pleasure to be gained from Michael Pollan's clear, insightful writing. I actually had to abandon the book after the second section because I just couldn't take it any longer. I feel cheated - of my time, of my money, and of what could have been a wonderful listening experience. Audible.com should have a free short listening sample from each book so you can make sure the narrator is not going to ruin it for you before you spend your money on the whole book!
If you can tolerate his nasal, whiny narration, go for it - the material is fantastic, and everything one would expect from Michael Pollan.
