My children started watching this a year ago and became hooked immediately. As I try to keep track of what they watched I made sure to watch the first few episodes with them and found that the show is insightful, well-written, funny and teaches lessons without being demeaning or patronizing. The writers have a fantastic sense of humor and have developed a truly sophisticated world where good vs. evil isn't always black and white and choices are not always easy to make. I highly recommend this to any parent of a child age 6+ or any adult who simply enjoys good animated series.
