Not really. At least, Inherent Vice isn't any kind of sellout. I refer, of course, to the question of whether the great man himself broke his self-imposed silence by narrating this book trailer. I kind of hope he did.
The book is pretty good, I think. It traces a lot of the same trajectories as Vineland and Lot 49, but in a much less thinky way. It's almost as if Pynchon, in his seventies, has decided to leave the coming generations of readers with a book that will serve as a zippy, fun gateway drug leading to the rest of his oeuvre.
