Story: The drama is manly about an anime otaku falling in love but if you notice along the way... It is about much more. It is about the other characters as well. They like Densha have their own hobbies and situations and are all looking for a way to connect with other people cause they also feel ALONE. They story is sometimes really funny and hilarious but between all that you ca really feel the loneliness of the characters. They all at some point see themselves in Densha Otoko and by helping Densha they also start to make changes in their lives. This is in part what I think made this a best seller and popular. Densha Otoko is great not only because it has a good romance story but because we see Densha Otoko and the other characters grow up and feel better on their own skin. They felt loved and accepted no matter what their hobbies or situations are.

Acting: They all did perfectly. Even the all over the place side characters. You never really get to know all the random people replying to your posts online so them trying to show us a sneak peak of that was awesome.

Music: After listening to Twilight so much I had to look it up and it was well selected. The lyrics and music style fits with the whole theme.

Rewatch Value: I would recommend to watch it at least once in your life. For me once is enough.

Overall:
After looking at the comments I think that to enjoy this story you have to look pass the "over acting" and look deeper into the characters and overall story setting since this is inspired on "actual events". Take note that back in the early 2000 there was no facebook, instagram, twitter or social media in general. Back then we had forums. This drama represents that era masterfully. Forums used to ruled the internet back then. We used them to look information about our hobbies or just to simply rant off... express our troubles to strangers looking for comfort and support.

I loved this drama cause I've been there. I used to spend time... actually hours in forums and like Densha Otoko I got to meet a lot of nice people online that later on became great friends offline. We where all young looking for a place to fit in. And believe me some might say it was over acted and perhaps they are right but the feel of been lost and like you don't belong it is real. It is nice to find people you can relate to and that can understand you without "judging" you. I'm grateful to the people that helped me out through my darkest days and helped me fight my depression.

Also since I love anime this drama hit right home. If you are into anime and more tech related stuff... you will enjoy a few things like the several homages to the anime culture, references to Gainax and animation studio Gonzo who made the anime sequence. Also the use of Alt characters symbols (Shift_JISart) to make the full images on the forum board. All this made it AWESOME!
