I'm very much looking forward to this one, and love the darker turn that the series is taking.
Have to admit to liking some of it's cartoony predecessors, however. The series/movie from the 60's has long been one of my favorite guilty pleasures. I am also a huge fan of the Burton films, which managed to capture both cartoony and dark in his typical style.
As for the Schumacher abominations... just a shame. I actually kind of liked the first one, even though it was pretty awful, just because Jim Carrey made a good Riddler in the Frank Gorshin vain. The second one was so embarrassingly horrible that I'm still surprised it didn't kill the franchise completely. Which is really a shame since I think George Clooney had the potential to make the most interesting Batman/Wayne. Especially if they'd used him for Frank Miller's older/hardened/jaded depiction of Batman.
