I heart Klosterman. This is a geek I'd get along with. For one thing, his writing style sounds like my inner monologue. He's sarcastic and obsessive about things that less geeky people couldn't care less about.
This particular tome definitely skews into the metaphysical. Klosterman seems quite hung up on the construction of reality. Or the impossibility of reality. On irony and our inability to communicate with genuine people (like Canadians). It sounds complicated and boring, but it isn't. It's like me making every life event relate to Sienfeld or Friends.
His essay on how progressive the NFL is left me a little cold (even with extremely detailed foot-notes, there's only so much you can absorb if you haven't spent the last 2 decades watching SportsCenter daily). The essay on time-travel was equally detailed, to the point of being almost unfollowable, but if you love Back To the Future (and seriously, who doesn't?) the first three-quarters is priceless.
Also notable - interviews with documentarians, tales from Klosterman's days in Fargo and what may be enough evidence to arrest him for being a peeping tom. Lengthy commentary on how much we've failed to learn from the Unabomber (hint: he's crazy, but not wrong).
As with all his books, I enjoyed this immensely and recommend it to anyone who suspects that their reality is a figment of their imagination.
