I'm a fan of John's earlier films this is a underrated TV Movie before Saturday Night Fever and Grease, he's unforgettable as lonely teenager Tod Lubitch born without immunities, he falls in love with neighbour Gina, attend High School dressed in a very cool space suit and long to hear news of a cure, the ending of the film could have been better it's a mystery as to whether Tod lives or dies, a must see travolta movie.
