I saw my first episode of Black Hole High, as it is called in Australia when I was 4 years old. It scared the heck out of me and I thought Josie was going to die.... I was horribly mellowdramatic because when I came back to reruns at age 8 I loved it soooooo much. It subtly teaches some good science lessons among all the random black hole stuff and every episode has an underlying moral (e.g. Lucas shouldn't wish his youth away, Josie needn't be critical of her appearance, Vaughan and his father are more alike than first appears). It is of amazing quality and the cheesy jokes are the best!
