The Creature introduced me to science fiction! I caught it on TV one day as a little kid and was hooked on the exotic stuff from then on. I always loved how it took the whole crazy "quest for the missing link" logic and shoved it even further back -- to the missing link between fish and man! And the Creature looked good -- the very first story I ever wrote was about a man who finds himself on a planet where everyone looks like the Creature.
Plus, it was so easy to root for the Creature -- poor soul (sole?), all he ever wanted to do was get his webbed claws on Julie Adams or Lori Nelson ...

I'm also fascinated by werewolves -- but as deliberate, self-controlled, intelligent shapeshifters, the whole old berserker thing doesn't do it for me.
