In almost all of the scenes meant to be sympathetic with 電車男, I honestly felt cringe and even a level of disgust. All the sniveling and crying and stuttering >_< Also, is 電車男 genuinely kind, or just too weak and scared to stand up for himself? I think his devotion mostly comes from a self-awareness of his loserdom, and a lack of self-respect. He's so self-sacrificing because it's his only viable strategy in competition with an army of ikemen.
Also, his infatuation with Saori is purely based on looks, and an ideation; a mental image of her he created after their first meeting. He doesn't actually get to know who she is, because their relationship remains surface-level throughout the whole show. I learned nothing of much substance about either of them.
All that is to say that I don't think he's a saint; he's a simp, and kind of pathetic (but he doesn't have to be!).
Reminder that in real life, Ito Misaki, the actress playing Saori, married a handsome CEO.

Otherwise, the show has some merit: the way the forum discussions are presented is cool; the kaomoji master is a true artist; Shiraishi Miho and Toyohara Kosuke's characters are great - they're good actors; Ito Misaki is beautiful, and this show gives her a lot of screen time. I also really like the Jamaica pouch Otaku's raspy voice.

Overall: as a romance, it failed for me, but I thought it was a solid comedy :) Mostly due to the talents of Shiraishi Miho and Toyohara Kosuke <3
