I know web comics can be of wildly varying quality, but I stumbled onto one I'm reading right now that's REALLY good and interesting. Also, pretty damn twisted, but it's sorta moving past that.

The art was a little off-putting for me at first, but you adapt to it pretty quick and the story is pretty weird and awesome so far. I think he puts out a page a day and is up to like over 200 pages so far.
