I think the Riddler is one of the more malleable Batman villains...In the right hands, he often becomes one of the most memorable Batvillains, unlike his status in current batcomics. Before the 60's TV show, Riddler only made two appearances in the comics....after Frank Gorshin was done with him, however, he became one of Batman's top villains. Fanboys can whine about jim Carrey all they want, but among the general audience, he's pretty much second to Jack Nicholson's Joker as the most popular Batvillain from the Burton/Schumacher series. I'd be slightly disappointed because if a truly good actor is allowed to work with Riddler, his status could be elevated again....
