Alan Moore for me is the penultimate example of this phenomenon, or perhaps it's more accurate to say that he could be the penultimate example. I've read/watched enough to recognise the impending symptoms and exercise ruthless discarding practices. I've read, in chronological order, League book 1 (interesting), V for Vendetta (loved it), League book 2 (OMG, what images have I imported into my brain) and the first few chapters of Watchman (too repulsive to continue). Despite swearing off Alan Moore after LXG volume 2, I got persuaded to start Watchman against my better judgment - only to sit shivering in a corner of the couch for half an hour after I pried my fingers our of the cover. Perhaps I need to be more ruthless...
