I loved the black humour in the movie. And somehow the classical tunes emphasized it.

Shogo and Shinji are eye candy deluxe as are Mitsuko and Takako. *.*
I didn't like movie!Kiriyama. But I loved when Shogo came back to get his bag and bumped into Kazuo on purpose! No wonder people like to slash them.

I'm glad I've seen the movie first of all there is to BR. I'd have been disappointed if it'd been the other way around.
