That didn't get cancelled in the sense of ratings or anything. Basically Raven and Annaliese van der Pol both looked like they were in their late 20s and they were trying to make out that the characters were 16. Disney have this all the time with these teen programmes, and don't want them to end up like Sabrina the Teenage Witch - where the main character was trying to play a high school girl, but looked like she was nearly 30.
What was my favourite show that was cancelled?
Caprica. Given the success of BSG, I think they could have at least finished the season.
And Law & Order. Clearly the characters weren't the problem as they went and exported them to other parts of the franchise, and SVU is still made.
