Negima has become one of my favorite anime series. The story is pretty good for an anime, and when you have a 10 year old magic instructor teaching a classroom full of 20+ girls, there is never a dull moment. The main eight-or-so characters are adorable, and there is good character development on them, we eventually learn a little about all the students. The story is pretty light for awhile, with a lot of comedy and slice-of-life episodes that help you to understand the characters better, and build up an overall story line. The most surprising thing about this series is whathappens in the last few episodes. The story line takes a sudden turn towards the serious, and the drama that unfolds is riveting and heart-rending and will keep you pressing "play" long past your bedtime. There is a lot of fan service and I would definitely put this anime in the PG category. Overall, I think it is one of the best light-hearted animes out there, even if it is in the harem category.
