I don’t give a damn about overrated characters. As long as no one is seriously underrated (like, as good as no doujins, fanarts, etc; nearly nothing) I really think no one should care about that. It shouldn’t mean something to you, if someone’s overrated. Just like whatever you like and enjoy it without this nonsense.
I honestly prefer it when Touhou, while still full of powerful beings, is light and soft, with no Youkai except the feral ones actually eating humans. I don’t really mind dark interpretations either, but the light ones are still my favourite.
