Fanon
The Animated Series
Sorry, I'm a naturally jaded person. Add to that working off of 2 hours sleep thus making me a little cranky right now.
I'll wait for reviews personally.
I think it's strange people get so agitated about fanon being used in, well,
fan-works.
Also, there is possibly no other series in existance that goes so well hand-in-hand with fanon as Touhou. ZUN is basically the patron saint for the 'Sure, Why Not' trope. He made the China nickname official, he gave Momiji the detached sleaves plus wolf feature look in one of his novels (
she had neither on her game sprite in MoF. Those blodges on her head were shading and there was no tail visible. Fans added them for extra moe) and he also made Daiyousei's and Koakuma's name official, lampshading Alice, Marisa and Reimu's fan potrayals in Meiling's dream and much much more, all of which was thought up by fans.
I think the fanon just adds more to the whole of Touhou. An extra dimension if you might say so. Most of it provided the extra humor, awesomeness and allure of the Touhous, and it isn't that farfetched or annoying. If it wasn't for fandom, most of the characters would be pretty empty and lack alot of characteristics.
Although, some ARE pretty annoying (Suppa Tenko Ran comes to mind. I don't care for Alice so her mood swings don't bother me that much.)
