So my intention here is discuss story or setting choices that in hindsight were maybe not the best idea.  I like the series but it's been around for nearly two decades and 15 books (plus a lot of short stories)  As such, some things have not necessarily aged well and others turned out to not to have been such a good choice with how the story has progressed.  That said if people want to talk about things that occurred in recent books, that's fine too. 

Off the top of my head I have two:
1) As discussed in another thread, I find the idea that black magic inherently corrupts a person (and as such the Blackstaff is needed for the White Council's dirty jobs) a poor choice.  I think the idea works in Molly's disfavor and is honestly less interesting than the idea that such corruption is based on the person using the magic and not vice versa. 

2) Wizards inherently have issues with technology.  To be fair, this was presented in a pretty silly way from the start.  Harry talks about how he naturally can cause issues with firearms which is ridiculous (although the books do drop this as time goes on).  Like I can understand how Wizards can screw with electronics, especially delicate things like computers (as it is computers in our world can have issues with outside energy sources).  But guns are pretty simply machines, even the fancy one's.  It'd be like if being a wizard meant you'd have cause a bicycle to fail.  I could understand that a wizard could, if they try, bend the laws of nature.  I mean that's what they do.  But to inherently prevent things like combustion or lever or gear or springs (for example) from working is just silly. 

That said, for actual tech like cell phones and computers, I feel that wizards being unable to use them is kind of meaningless for the story.  Like, the White Council could still be behind the times simply because institutions are slow to change plus most of its members are pretty old (so no one would have thought of Paranet before Harry did).  Similarly, Harry can still be on his own early on because for instance no one can get to him in time or he's purposefully keeping them out (which is something I did not care for, but it seemed like Jim intended for it to be a flaw of Harry's so its not an issue). 

Bu the world now is significantly different from the world of 2000 (when the first book came out).  So much stuff is online now and even things like newspapers are dying out.  It struck me how Harry had to use a pay phone in Storm Front.  Now they're non-existent which for the series would make it so much harder for Harry to update/get in touch with others.  Like the only way for Harry to make calls is from his house or someone else's (or to do so magically).  This ends up cutting him off from his supporting cast to such a significant degree that it seems like it'll cause issues for the stories.  Honestly, this doesn't seem to add anything for the  story but does cause issues.  Plus other series in this vein let their wizards use tech and it doesn't seem to cut off any story potential.

So I finally got around to reading through my compilation of this series and man it was bad.  Dialog that didn't match the art, there's one page of dialog that was seemingly in response to something that was never said.  The fed's clothing changes between the end of the first issue and the beginning of the next.

Also Harry Dresden was seemingly very out of characters.  He's so full of rage but the story provides nothing to explain why he has so much rage (to the point of almost beating the crap out of some kid who ran in front of Dresden's car).   

Finally, it seemed inappropriate that Dresden keeps calling the Wolf People Dog Men even though Listen-to-Winds made it clear they were called Wolf People.  Dog Men was just used as a possible description by one of the people who saw the attack. 

I liked the other comics that have been produced but after this one I think I may be done with the comic version of Dresden.
