I think they could manage it, too. I'd just very much hope that they'd follow something a lot more like the way Game of Thrones is being done for HBO, rather than the way they handled the original material in the first show. GoT tries to stay very close to the books, and as such, they're pretty much as good as the books are. They did ten episodes to tell the story of the first book in the series. The Dresden show made one episode approximating Storm Front. And for the rest of the show, they seemed to be trying for a monster-of-the-week thing. Why bother using source material as good as the Dresden Files if you're just going to ignore almost all of it?
So, if they try to make another Dresden TV show, I hope they match it a lot more closely to the books, rather than following the creep-of-the-week format.
At some point last year, we had a big discussion on how we'd approach the show if we were starting over from scratch. Don't remember which thread that was in or if it's still around. Anyway, my idea would be to have HBO or one of the other premium networks do the show as a season of 10-12 one hour long episodes. The first season could contain the first three books, the second season could possibly cover the next three, but after that it'd cover two books per season, giving each book a solid 5-6 hours of screen time. These books aren't nearly as long as GRRM's, so they wouldn't need a full season per book, as squeeifying as that would be. If the books got the premium network treatment in that general format, I think it would most likely be a phenomenal production.
Alternatively, if a regular network picked it up for a ~20 episode a season schedule, they could do three books a season. Provided a decent budget, that could also be quite a good production. I absolutely agree that they'd need to follow the books, though, none of that random monster of the week crap. You know, I don't mind if they make some slight creative changes to the stories to make them work better on screen. Like changing Murph's first name. No problemo. Heck, they even can add in or drop some ancillary characters or locations and it doesn't bother me. Just when it gets to changing around entire settings, characters, and storylines, that's when I lay down and throw a spectacular hissy fit.
Ooh, if they wanted to torture us and force us to surround the network HQ with barrels of tar and bundles of feathers, they could turn it into a half hour sitcom and have it be told from Harry's POV a la
How I Met Your Mother, except it would be Maggie sitting on the couch and the show would be called
How I Killed Your Mother. 'Course, that would only cover the first half of the series, up through
Changes, but hey, it's an idea.
