I've gotten to the point where I can barely sit through most modern Japanese films. It's as if I've been sensitized to the banality-wrapped-in-perversion that seems to be the common theme of many Japanese films.
I admit that I haven't seen a ton of recent films, but of the last five or so, I literally had to turn them off half way through. Miike hasn't made a good film since Audition. So many of the characters seem so hollow, and you don't really care what happens to them. Also there's this kind of weird isolated loneliness that pervades most Japanese films that I can't stand anymore. Anime, in particular, is guilty of this. It's hard to explain exactly, because I'm definitely no film critic, but I just have a hard time getting into the film now days.
I've actually really enjoyed many of the Korean films I've seen recently, and even though some of them are probably a little old, they have kind of recaptured what I used to enjoy about good Japanese films. Memories of Murder was particularly good...and although the story felt kind of closed-off and isolated like a Japanese film, it wasn't lonely, and you didn't mind being trapped-in with the characters.
But I'm willing to keep an open mind, so if anyone has some suggestions for good Japanese movies not on the above list, feel free to offer them.
