I finally got around to watching this show over the summer and loved it. Brian happened to be reading the book at the same time I was watching the show and he really liked it, so I thought I'd give it a read.
Normally, I don't like to watch something before I read it, but in this case, the show and book are so different, that it didn't matter. The show takes an interesting look at the lives of the other prisoners, whereas the book really only mentions them and does not talk about their stories at all. Even the main character's storyline is different between the two.
Of course, there is much more drama in the show than the book. On the other hand, I'm sure the book gave a more accurate depiction of life in low security prison.
My rating: 4/5
