Even being a huge fan of the Nolan films, I find it hard to understand how someone could think The Dark Knight was an improvement on Batman Begins with regards to feeling overly self-important.
For the record, I can totally understand Sven's liking the Schumacher and Burton films better than the Nolan films. It's not "contrarianism" as so many seem to accuse Sven of sinking to - they really seem more up his alley both stylistically and tonally. When I look at the comic books (and the versions of popular heroes that he most enjoys) I totally see a more stylistically adventurous film like Batman Returns or even Batman Forever being higher on his list than the admittedly self-serious, dark, and loosely "realistic" version that Nolan committed to film.
I don't mean to commit the same crime of speaking for Sven. My intention is only to say that his opinions on the series' totally make sense.
Oh, and have I mentioned yet how animated Batman is the way to go?
