There is no question that the 5th (and last) season of a "Hazel" was by far the worst. But this particular episode Is the nadir of the entire series. It's downright embarrassing.
This episode was made in 1966, about two years after the Beatles' immensely successful arrival in America, and the same year that NBC began "The Monkees" hit TV series, yet the out-of-touch writers here are so confident that everyone hates long hair and rock music that they blatantly ridicule what they assumed was a passing fad. Little did they know that six years later, virtually every American male would be sporting long hair, and that rock would become the defining music of America for the next several decades.
The episode is made even worse by the fact that the young actors involved, who were around 14 at the time, look like elementary school students, and seem silly even talking about forming a serious rock band. But not nearly as silly as the adults here or the writers, who were definitely out of their element.
"Hazel" was a great sitcom at start, but it went on one season too long , and this inane episode is simply cringe worthy.
