I've been an Alan Moore fan since Swamp Thing #40, the first Moore comic I read. One thing about Moore's writing is that he seems to be able to come up with amazing concepts on a regular basis. This doesn't seem to have gotten less true as the years go by either. I was unexpectedly surprised by much of his America's Best Comics imprint as I was by his work for DC in the 80's. One good example of this is in Tom Strong #9 (Sep, 2000), The perils of Dhalua, Volcano Dreams. Tom Strong is a pretty strait forward action comic though the stories tend to be more heady than your normal comic. In The Perils of Dhalua Moore surprises us with a great twist that just stunned me the first time reading it and left a strong impression.
