I never judge a writer's work based on whether or not I care for his personal beliefs, individual temperament, private practices, or public excesses. Rather, I believe we should confine our judgment to the work itself. This is a largesse I think should be extended to all writers, whatever their medium or genre might be. ALL. WRITERS.
If the author is willing to keep themselves out of a work, I'm willing to return the favor. But like it or not, Sim is a character in /Cerebus/, and rather more of one towards the end than the supposed protagonist.
In this case I'm limiting the domain of my remarks to authors who quite literally write themselves in as a character and/or engage in long chunks of raw didactic essay plopped into the middle of a storyline. No quoting of Foucault's "What is an Author" needed here, really.
I actually bought a few phonebooks off of eBay and to my extreme pleasure found out that the seller was Mike Heisler of DV8 fame.
I enjoyed Cerebus without thinking too much about Dave Sim the person. I'm sure there are creators that I love in all media that I would cringe in their presence as well as creators I'd enjoy having dinner with whose work I didn't enjoy. The work itself was enjoyable and pretty to look at while making me think a little. That's all I can ask of anything anybody creates.
1. I've never been much into fantasy. I enjoy reading Conan stories, Gaiman plays with those concepts well, and Fables barely counts as such to me, but other then that, I just can never get into anything that has wizards and magic and stuff.
2. While I can read authors who's opinions I don't completely agree with, the way that I've always heard it, Cerebus literally became solely about his horrific views on women after a while, and if I wanted to see extended monologues about how all women are talentless, soul-sucking cunts, I can just go to the seedier side of the internet for free.
It's also not really fantasy, it's a lot of things. So both of your points are off mark. Just give it a read and see for yourself. I would recommend reading the first two books, as the first one's no indication.
