Junji Ito makes some beautiful, beautiful pieces but his stories are so utterly nonsensical and cruel that its hard to have anything more than a momentary shiver. If manga aesthetics can get you to you, Morohoshi Daijiro has some excellent work. The first work talked about here, Ankoku Shinwa, I have printed and framed several of the final pages because of their deeply affecting power.
