There's lots of interesting viewpoints presented here, but the book loses points for some seriously sloppy copyediting. There are duplicated sentences, missing commas, and even characters names spelled wrong. I know things slip through the cracks sometimes, but it got to a point that I could no longer ignore it.
I also wish it had been compiled after the new series was finished, it only goes through season three, but a some of the arguments presented necessarily change with information presented in the final season. Not all of them, obviously, but I still think a complete view of the series would inform many of the articles more fully.
