Which Batman actor is the best actor film in Batman movies of all time?

For me, it's Michael Keaton. Because Michael Keaton play his role as a
Batman/Bruce Wayne very good. The part I like the most about Michael
Keaton act in a film of Batman (1989) and Batman Returns (1992) is
where he fight against the bad guys. It's really awesome and very
classic. The storyline also not so bad. Great storyline. Although
Michael Keaton is no longer play as a Batman/Bruce Wayne now, but to
me, he is the best Batman actor of all time of all the Batman films
actor and I consider him as a Batman legend. What about you? What do
you think?
