In general, I enjoyed it. I saw the show before I read the books, so I didn't have the problem of having to compare them, and in retrospect, it differs significantly enough from it that I can dissassociate the two from one another without a problem. I really liked the actors, and the dialogue was excellent. I LOVED TV Bob, an excellent rendition of the character. I didn't mind the hockey stick, and I still picture Harry's blasting rod as a drumstick whenever I read the books (though, granted, it was more like a sonic screwdriver in the series  ).

That said, there's a few things that I didn't think were that well-handled. I was mostly irritated that Harry just didn't seem to use enough magic - he seemed more like a paranormal private eye who casts the occasional spell now and then than an actual wizard. That, and I found the friendly neighborhood vampires and infecting-bite anthropomorphic werewolves a bit generic even before having read the books. Oh, and I couldn't help but think "What ever happened to that Susan", who came out of nowhere in Storm Front and was nowhere to be seen after.

All in all, an enjoyable series, and it got me into the books, which are the most enjoyable and engaging ones I've read in years.
