Except for audiences in Japan! And yes, I will openly admit that I say those words in a slightly "so there!" tone.
Apparently, The Dark Knight has not done incredibly well there, pulling in just under $9 million in the three weekes it has been in theatres in that country.
Slash Film provides a possible reason for the underperformance abroad:
The story is very pessimistic. It has a dark and gloomy texture that Japanese movie fans do not find appealing in a ‘comic hero’ film… Japanese movie fans expect such films to be fun and action packed, for the hero to be attractive, for the villain to be loud and outrageous, and for the movie itself to be easy to understand and light.
Indeed, I did not feel titular character in The Dark Knight to embody the notion of the "comic" nor a "hero."
Although, Christian Bale is definitely attractive (see: American Psycho if you have any doubts), so there's one big check-mark going for it.
