Densha Otoko (WikiLink)
What's it about?
Nerdy guy saves a beautiful lady on a train and has no idea how to date her. His otaku friends help him via chat.
What do I say?
Allegedly a true story. A really famous jdorama, too, so kind of a must watch there. The story itself is indeed kind of cute, but the main character is really whiny which gets on your nerves after a couple of episodes. And the girl looks way to old for him. On a side note, she has a fiance who is sold to us as "really good looking" but he's got that really weird beard and looks like he should wear a trenchcoat and lurk in dark alleys looking for unsuspecting school girls.
But I digress. On the plus side, the main theme by ELO is really catchy ("Twilight" - if you ever go to Tokyo, Akihabara, this will be blasting from speakers everywhere - otakus love their "Densha Otoko"). Also, it stars a couple of people before they became famous, like Oguri Shun, Hayami Mokomichi and Horikita Maki. Overall, OK to watch, but not brilliant.
