Kikujiro, directed by and starring Takeshi Kitano, is such a lovely little film. I saw it for the second time the other night and thought I'd come on here and recommend it to you if you haven't seen it.
I believe didn't get much support from critics when it came out, but to me , it's well up there with his other films. It's a refreshingly non sentimental story of a kid searching for his mother. He and Kitano, who plays an ex-yakuza, have some surreally funny moments along the way. I think it's a wonderful film. :)
