Entertaining, to a point, but mostly just an interesting idea, since Ouellette mostly uses episodes and events (sometimes just flimsy scraps, like the fact that Oz has a band) as excuses to talk about scientific concepts (usually quite briefly, and - particularly when it comes to quantum physics and string theory - not very clearly). The book skims over the surface of both science and Buffy, and disappoints me as a fan of the show and of science writing. Oh well. It got me through much of the journeying to Singapore.
