A friend loaned me the DVD in January. Loved it, loved the characters. by episode 4 I learned there was only one series and noticed the Based On...tag for Jim Butcher...ooh, there are books! Finished the series, bought the first book and despite realising immediately the set up was pretty different the characters obviously grew tenfold with the unlimited scope of writing vs TV restrictions. Hooked totally. I have bought maybe 20 books in the last 30yrs...14 of them are Dresden Files downloaded. might have to get the hard copies for re reading old style :-)  Already bought and rewatched the DVD!
