-Deadman was very different from the clean cut superheroes of the silver age being crass, uncouth, and occasionally unlikeable.
-The Deadman run in Strange Adventures can be looked at as Neal Adams' breakout work, predating X Men, Green Lantern/Green Arrow, and Batman with Dennis O'Neil
-People make fun of Adams' writing now on books like Batman Odyssey, but his tenure as writer on the original Deadman run was still miles ahead of most comic book storytelling at the time, with many twist and turns that still surprise to this day.
No one's saying thaf Neal Adam's Deadman is up there with say, Watchmen, but I'm surprised it doesn't come up in the conversation of the best comic books, and it tends to be overshadowed by his runs on Batman and Green Lantern/Green Arrow.
