I loved Sonic X, however I only watch the Japanese version, which as sad is it might be, I have never actually finished the series. I watched it mainly because of Amy, Shadow, and Cream. I didn't care much for Chris. I don't hate him, but I don't like him.
I wish there was a fourth season honestly. They could have brought in Silver!! Now that would have made it interesting. Or maybe have brought in Mighty the Armadillo to work with the Chaotix. If they had Mighty I would have loved the show even more.
