Though it may seem that the concept of the teen idol is an old one, it is actually rather new in terms of cultural history.
The 1999 TV movie, Ricky Nelson: Original Teen Idol, tells the story of the late actor/singer Ricky Nelson (Gregory Calpakis). The younger son of Ozzie and Harriet Nelson (Jamey Sheridan and Sara Botsford), Ricky was a performer from a young age. Starring with his family first on radio and then on television on The Adventures of Ozzie and Harriet, he was sold to the then young audience as a heartthrob. Then as he aged (as many young performers experience), his name fades from the headlines and he has to deal with no longer being in the spotlight.
Though the narrative is by the book, the story is familiar to anyone who has seen the trajectory of many young actors and singers. After being in the limelight and dealing with everything that comes with that while growing up, they become an afterthought or a piece of nostalgia when the newer model comes along.
Do I recommend it? Maybe.
