Shoujo anime is one of my favorite genres when done well. That's why anime like Skip Beat, Nodame Cantabile, Kimi ni Todoke, and Kare Kano are among my favorites.
Maybe I should list my recommendations, too.
How about josei? Chihayafuru is just epic.
I started to type that but didn't since it's not technically shoujo. Then again, I think Nodame Cantabile is josei, too.
Chihayafuru is one of the best anime/manga of the last several years. In fact, I've been thinking about rewatching the first season soon, possibly after I'm done with the Yamada and the Seven Witches drama.
Josei has such a wide range but it does include many of my favorites like Nana and Princess Jellyfish.
