Sorry, I know there is a nostalgia for Batman 89, but I saw this in the theatres. Although I've grown to appreciate its positive qualities over time the worst thing about the movie for me was easily Keaton. He didn't look or act like he was capable of changing a tire, let alone being Batman.His Batsuit was horrible, designed to compensate for the actor's physical stature, that created a type of Batman that relied heavily on technology rather than his innate physiology. As Bruce Wayne, Keaton just missed the mark as well.
Well observed.
You have Burton to thank for that horrible miscasting. I recall the 1989 NBC interview where he said he wanted Batman to be (in his words) a "techno-geek" instead of (again, in his words) the "square-jawed hero." Wrong for Batman from the start. As is the norm for most Burton films, his own insecurities/obsessions were dumped on the polar opposite of the kinds of weird and/or misfit characters that populate his movies.
Casting a short, blading, unathletic, and gravely voiced comedic actor to play one of the greatest and most physically defined (and occasionally dashing) superheroes ever created was bull, and beyond disappointing. Val Kilmer has ever been my cup of tea, but he made a superior Wayne/Batman--by leaps and bounds--over the dumpy mess that was Keaton.
Thankfully no one will ever go in that direction for a Batman movie ever again.
