I think I grabbed this audio book to fill out an order from bn.com , and it was such a quick read (three discs) that I am almost embarrassed to include it in the count. Oswalt is a geek that does stand up comedy, so you know that there are going to be self-esteem issues.
The title comes from an idea that, "before all young minds have anything to write about, they will home in on one of three storylines: zombies, spaceships, or wastelands". He argues that Darth Vader is effectively a zombie on a spaceship that came from a wasteland. OK, then.
Personally, I preferred vampires.
I like Oswalt's personal stories much better than his schtick (I totally could have done without the hobo chapter), and I imagine that the schtick does better on this audio version than in print. Also, there is a "bonus chapter" on the first disc that is not a "bonus" at all, but the pdf of a graphic chapter that couldn't be translated well enough into audio. Which you find out in Disc 2.
I could probably read Oswalt again. But I will not be seeking him out on Comedy Central.
