I was re-watching season one of Gotham and enjoyed the character of Ogre. Curios to know if there are villains like him? I mean in regards to the antagonist being charismatic, sly and superficially charming. The one I can think of is The stepfather but that's more family and not romance. Also there was an episode in Poltergeist with Geordie Johnson playing the supernatural lover who looks to seduce and trap women in to his dimension.
