EC Comics relied a little too heavily on formula to suit me. The 'poetic justice' plot was way over-used; some awful person mistreats someone in a distinctive way, and that victim turns the tables and gets revenge in the same way they were abused. If a man bugged his wife by insisting his clothes were pressed perefectly, she'd go nuts and burn him to death with a giant flatiron, that sort of thing. Half the time, the victim died and came back as a lovingly described walking corpse to get revenge.
However, when EC was hitting on all cylinders, they turned out absolutely great stuff. Here, from THE VAULT OF HORROR# 32, Aug-Sep 1953, is "Whirlpool." This story was written and drawn by Johnny Craig, and it really has that nightmarish TWILIGHT ZONE feel to it.
