That really does defeat the purpose of consuming any form of media, doesn't it? Titles like Utena and Lain for instance have a lot of imagery which allow you to piece together and interpret the ending in your own way, if you've allready been given an opinion you're far less likely to form your own. As for mystery type stories, there is surely no benefit of knowing the answer from the off, trying to solve it before the characters is part of the fun of these. I guess i'll say the same for Madoka, finding out snippets of information, using the the images that are thrown at you piece together the case of QB surely beats what you've done..... Well, I guess we all enjoy different things, I'll leave you to your fanart and unlimited rewatch works.
Ramble over.
I might actually go this time.
