I was waiting for this forever as I am a die hard Kame fan but as was stated in the other reviews the script was short on explanation and needed a little more touching moment between the married couple. Just when you think they are starting to connect the movie is over. That might be the issue if it was a 10 - 12 episode drama it might have felt smoother. Makes me wanna read the manga now.
That being said OH MY GOD KAME IS BEAUTIFUL. You get Odagiri feels in this and his camera time is amazing.
