I really enjoyed Train Man: Densha Otoko on a lot of levels.
It took me back to Japan, to many of the things I enjoy (or find intriguing) about the culture.
The politeness, the formality, the neon of Tokyo, the quirky mannerisms, and the structure.
At the same time, it had a surprising level of candor and brought a solid Western-like love story to the screen albeit in a uniquely Japanese way.
I thought the acting was very good and the script even better.
For those of you who have lived, traveled, or just want to go, I'd recommend this one.
