As well... social anxiety? Sometimes there is no cause.
Just like depression.
Yup, everything has a
cause, technically speaking, but when someone talks about a "cause" for a mental illness, they usually mean some external trigger or social set of events that "explains" why you feel like that. The main problem is that if you understand it like that, then
"get over it" becomes good advice for chronic depression sufferers, or your friends think that sticking someone with crippling social anxiety into rooms packed full of people to
"get used to it" is a good idea. So that's why trying to come up with external "explanations" for why someone turned out a certain way can be harmful to understanding real sufferers. People basically project their own psychology onto other people to try and explain why someone acts the way they do.
I'm not a big fan of the "it's the last episode, time to get serious" tradition in one-season comedy anime.
That didn't really happen in Watamote though, did it? IIRC it was open-ended enough for a S2 and matched the rest of the tone.
There's also probably enough source material for a S2, although the show was a flop so we'll never see one.
Yeah, Japanese Otaku not really digging shows that
reallistically depict otaku/hikkomori.
Welcome to the NHK also flopped in sales. I heard The World God Only Knows (about a Japanese dating game geek) also didn't go over too well in Japan, though better than the other two, since it's not so scathing about otaku. But in the West, such series are lapped up. Watamote and Welcome to the NHK, and World God Only Knows are relatively much more popular. Maybe this is because "geek" doesn't carry the same negative connotations as "otaku".
Japanese Otaku only seem to like media about otaku that make them look good. e.g. shows about Hikkomori otaku who go to a game-based fantasy world, and suddenly lose their social inhibitions like magic, and/or get all the girls.
Contrast total flop of sales of Watamote to the strong sales of Himouto Umaru-chan. I liked both shows though. Umaru-chan is about an adorable otaku girl, who projects a Ms Perfect appearance when outside her house, so she has to hide her banal interests behind a socially-acceptable facade. It's a good contrast series to Watamote, basically the settings are similar yet complete opposites. That sold like hotcakes in Japan.
I wonder if some series will (or do) get enough overseas sales, so that the Japanese studios basically end up making them mainly for export. But they have to be made in Japanese, air in Japan to "keep up appearances" for the anime street cred. Watanabe's
Space Dandy would be one possible suspect for this. It was simulcast in English right from day one, and was clearly aimed at people who loved Cowboy Beebop, plus some things reminded me, very vaguely of Futurama. Additionally, it didn't sell all that well in Japan from what I can tell, yet still got a second cour.
