Me too. Although one of the challenges of using that character is trying to make sure he doesn't seem too similar to The Joker. If Nolan does use The Riddler, I hope he figures out how to do that. In "Batman Forever", both villains were at times like lesser versions of The Joker. I had this Harley Quinn comic book where Harley Quinn calls The Riddler "a poor man's Joker" and he gets pissed off and goes on this rant explaining why she's wrong and he's much smarter and more mature. It was pretty funny.
