It depends on how the show is spoiled. If I'm simply told the outcome of a certain event in an anime/manga 100% of the time it flys right past me and it never hinders my experience at all. Only if someone explains exactly how that outcome came to be + showing images, maybe I'd feel spoiled. But even then, hearing a spoiler about an anime I haven't seen never ruins the experience for me because I simply don't trust other people when talking about anime and I assume they're explaining things wrong or leaving major parts out. Leaving me to do my own research of the series in question.

What I'm saying is - spoilers only ruin your experience if you let it... so dont. 4head
