I caught some of
My Little Pony: Friendship is Magic recently on tv, and ... it is legitimately, unironically excellent! Creator, Lauren Faust intended the show to be an intelligent cartoon for girls that boys and adults could also enjoy. And so far it seems like she is very much succeeding in that goal!
It has a large cast of strong and diverse female characters who all have unique and interesting relationships with each other. The main character is a bookish, practical and initially ant-social pony named Twilight Sparkle who's told by her mentor to make some friends. She eventually meets five other ponies who help her defeat the main villain in the first two episodes. It's a delightful cartoon with wonderfully done characters and some very clever writing. There is also highly entertaining musical numbers! Here's an example from the second episode:
The ladies are wonderful and the main protagonist is like a pony version of Lisa Simpson in many ways. I strongly recommend it!
