No, I did not like Micheal Keaton's Batman.
Physically, he was the wrong choice. I realize that Burton wanted him to be the "everyman". But, this just shows that Burton didn't understand the character of Batman. Batman IS NOT the "everyman". He is the ULTIMATE athlete, the ULTIMATE fighter, he is the pinnacle, he is quintesential man. The DRAW to Batman, is that with ENOUGH TRAINING, you can become this perfect fighting/thinking machine. Not that just any short, middle aged, balding man can put on a suit and save the city.
Acting wise, he was okay. He wasn't anything particulary great. He had some stupid scenes, mostly as Wayne, and his actual fighting wasn't that good. He delivered some lines very well ("I'm Batman" "Have you ever danced with the devil in the pale moon light", "I made you? You made me first".) But he wasn't anything terrific. He was a little less than solid Batman.
His acting brought him slightly above par, it was just his physical look that made him overall unconvincing in the role of the worlds greatest martialartist/detective.
