I personally thought "Densha Otoko" was an extremely moving movie. It was inspired by a true story and I think that's even more impressive as he was just like some of us, just blogging here on the forum like this one. The tale was overall a bit inspiring, but I do agree that the characters lacked depth and importance because their role other than supporting "Train Man" was otherwise vague.

I'd like to smile and think people will meet their 'Hermess' someday, just like he did.
