Yeah, much the same here -- I loved the first couple of phonebooks when they first came but gave up on reading Cerebus after Church and State II, the art was getting better and better but the story was just going off on all these interminably dull tangents and the characters were starting to not feel like the ones I'd come to love anymore. So I missed the first really blatant signs of the crazy that showed up a few books later, and by the time I heard about it on the geek grapevine, he'd long since descended into full-on crazy mode. I still can't bring myself to try to read the later volumes -- so much wasted brilliance put to the service of such insanity just seems too depressing -- but for some strange trainwrecky reason I can't seem to resist reading the latest OH DAVE SIM NO wank whenever it crops up.
