I really used to like Sinfest. Back in the old days.
I and still check it out occasionally hoping that it would have some good strips every now and then.
Honestly, back in the old days it could make fun of both feminism and chauvinism and pretty much everything. It had ROMANCE. Some of the scenes with Slick and Monique or with the nerd and the devil girl were just so beautifully done and he knew just how to tease with scenes where everyone but Slick and 'Nique saw that they're meant for each other. And that is not something that is easy to do well.
It have a very wide variety of subjects it could write about, but now the feminism saga is spreading like cancer into all the subjects in the comic and just killing the show. If it was at least some good kind of feminism and more than just "MEN ARE EBIL" then it wouldn't be so bad. (Actually, that I think is the thing that disappointed me the most. Ishida is a decent writer and I would have assumed that he could write about feminism and still write good, FUNNY strips...)
