Out of curiosity I watched episode 1 on YouTube about a month ago. It seemed pretty cool. So I watched episode 2. And 3. I have now watched all 52 episodes. The show is ADDICTIVE! Great writing, complex characters and good animation all combine into something far greater than just a "little girls cartoon".
Go ahead - join the herd (note: you might want to skip the first two minutes)
