Has anyone ever seen this?
Although most people said it was terrible because it didn't link with it's highly praised predecessor: sonic adventure, it was my favourite sonic series! The only thing I disliked about it was the disappointing ending as Dr. Robotic was defeated in two seconds and the characters never reunited with their mother despite the entire plot being about the reunion. I'm guessing a second series was initially planned but due to the bad reception (), they never made another.
Even if they don't make another series, I'd love to see Manic and Sonia to get into the original cast as they just disappeared. They are sonic's brother and sister, after-all.
