Wow, you've been watching anime much much longer than mine, so I understand. I'm actually honored to be able to meet some animes already finished. I can also relate I the movies I've watched.
I heard reading manger spoils anime adaptations, I may be wrong though, but how are you enjoying movies after reading mangas. The reason I'm asking this is because I'm afraid to start one as I don't want movie that has potential to be spoilt.
