I dislike the first modern Batman film quite a bit, and this is not even in comparison to the Nolan films, its simply was a lot of hype and didn't come close to living up to any of it...from the badly written hero, to the over the top but ultimately ineffectual Nicholson Joker, the movie wasted a big opportunity. In general the acting was pretty poor from almost everyone. While much of the production design was interesting, even the pre-CGI FX were inferior to many of the big budget movies of the late 80s.
I think the biggest hype going for the movie was that it was the first live-action non-campy Batman. So even being a Burton movie featuring Batman instead of being a Batman movie directed by Burton, it succeeded.
