As much as I didn't like it in terms of story, it's okay, but in the end, I'm just glad there are people will to put their entire time, effort and money to make a doujin touhou anime a reality. And because of that, I still like it overall for that fact that they are willing to do so.
In terms of characters, like I said, I don't mind fanon interpretation of them, I just didn't like how for the most part a lot of them seem bored or stressed, so they can't really show themselves as much (Like Marisa and the first half of Tewi and even Sakuya, though I don't really care about her anyways, she's imperfect anyways :V)
