Cardcaptor Sakura was an anime/manga that I really enjoyed watching. It seemes as if this was originally meant for younger audiences but it's clear that all age groups can ejoy this anime.
Typically, it is a magical girl anime but it also concentrates on her school life and there's a bit of comedy involved too. And even though CCS was a long anime (to me), CLAMP made every episode interesting and there were rarely any filter episodes.
Cardcaptor sakura is one of my favorite animes and I have already watched this series many times before.
