Voted Michael Keaton - I'm a big fan of the first two. I liked the Burton/Keaton films' balance between the Dark Knight and the colorful Adam West version. Keaton's underrated as an actor in just about everything he's in anyway. He's got a gift where he can take dumb dialog or matter-of-fact lines and deliver them in a way that gets a laugh, such as the exchange with Robert Wuhl in the first film:
"It's Japanese."
"How do you know that?"
"'Cause I bought it in Japan."
Great actors rise above bad scripts, and Keaton made a career out of it from the late-80s through the mid-90s. He even made date movie schlock like Pacific Heights watchable, which is a feat in and of itself.
