The best Michael Keaton Batman...
Out of the two films he did, which would be your favorite? I'd just have to go with the first film. I thought The Joker was far more effective in my opinion and it was the first time seeing Batman in a whole new and mysterious, dark, and Robin-less in a long time. Granted I was just three at the time of it's release, I'm a big Batman fan so yeah, hehe! I found out about that stuff a little later.
*The word "dabo" means "I will give" in Latin, and "Gold" in Aramaic.
J.J. "Binks" Abrams is taking over sci-fi!
