My favourite and most underused villain is The Riddler. I don't think he's been given a good story for ages and there hasn't been a faithful live action portrayal of him. He has so much potential. The best portrayal of him was probably in the Arkhamverse. Honourable mentions go to Mr. Freeze and Poison Ivy, both of which also deserve redemption in a live action film.

Most overused... The Joker... but deservedly so, in his case I don't think overused is a problem as he's such a great villain.
