I like it. Those who don't like non-traditional portrayals of comic book characters--or other classic literary characters, even--should realize that no portrayal will be the final one (probably not even the definitive one, although that word will be used). Each person who takes on the character interprets him his own way. The same's true whether you're talking about Hamlet, Beowulf....or The Joker.
Life's big enough for multiple visions.
