This focuses on the first three seasons of the original CSI, and primarily consists of extended synopses of the episodes. I suppose that makes it useful as a reference, if not especially fascinating - I'd rather watch (or more accurately, rewatch) an episode than read a two page summary of it. What's more interesting, however, is that each episode has an associated behind-the-scenes section, generally half to one-and-a-half pages long, that has commentary from the cast or crew. Sometimes that commentary is on character development, other times it's on how the story originated, or how certain scenes were filmed. It's new information, essentially - stuff you don't get from watching the show. No surprise that these were the bits I most enjoyed reading.
