Why?
well ...
in the last few years there have been quite alot of vamps, comics and other action tv shows, some of them are not all that bad.
I saw parts of the tv show, and it just wasn't good.
although, it was hard to see the changes done to characters.
bob being a human ghost or something.
I always pictured him as a voice coming from a ghost with eyes that shine whenever he is "on".
morgan being on something of a strict c.o. with dresden instead of a nemesis.
I didn't like it.
add to it, the scene in small favor when harry electrocuted that fallen angel with an electric cord, if you realy think about it, it all took place in 2 seconds, but in the book it was a page of fun action.
you can't take books into tv shows without real effort and probably alot of money to back it.
