Oh, I didn't read The Governor novels, so I had no idea. Really, he was never my favorite character in the comics either, but I think he works better - like Michael Myers - when he's just nuts for no apparent reason. Working the whole "Hobo Governor" thing into the storyline in that particular order still doesn't make much sense to me.
To a degree, these Governor episodes remind me of when Family Matters became The Urkel Show. Yeah, I know it's not on the same level, but it's the same principle - an (inexplicably) popular character who isn't all that interesting gets trumped-up screentime because the network is more interested in paying lip-service to the fans than making a cohesive product, or focusing on the core cast of the show. It's like Game of Thrones doing a Hodor episode.
Actually, no. That would be hodor.
