Personally, I like that old show, not despite the fact that it did not follow the books, but because of it. If it follows the books too closely, well, I've read the books, been there, done that. If it is sorta Dresden-like, enough so that it can at least be considered Dresden (even if only barely), but has NEW Dresden stories, and is at least a decent series (which I thought it was), then it's something new. Not as good as a whole new Dresden book maybe, but, well, it's something.
It could have been better, but personally I liked the acting, Dresden and Murphy seemed like themselves, even if he was too short (how many actors do you know who can play Dresden AND are almost seven feet tall) and she was a brunette (I thought she was the best part of the show, despite brunette and too tall).
I thought the show had promise despite clashing with the books. I hope the new show is closer to the books, but I do not need to see the books on TV, I have the books already, I want the TV to be NEW stories, but as close to the books as can be despite that. It should also be noted that writing for a book and for a TV show are not the same, example, I think Potter is dry and sparse as books but worked great as movies, and I know some books that are great but would not work as movies (maybe as a TV serial). Do not be surprised if the new TV show is not the books, because the books may not make good TV.
In short, I am hoping for NEW Dresden I have never seen or read before, so long as it IS Dresden.
