Seriously, if you aren't watching Princess Tutu, then what are you doing with your life? It started out a little weird and it ended with a really big bang, like stars colliding and stuff, only with ballet. Plus the music is amazing, but that's a given since all the music, minus the OP and ENDING, is taken from ballets, operas, and the like. A satisfying and conclusive ending leaves you wanting more yet you know it ends there.
Don't push it aside because of its cute appearance. There's something in it even for the most manly of men. I mean going en pointe and wearing tights TAKES ALOT OF BALLS.
