Great treatment of the complexities of relationships and the difficulty of making the transition from the youthful summer of life to the autumn of adulthood.
At the superficial level, Jonathan is one of the best students in his class while Shane is a trouble-maker who has no friends. At the request of Shane's mother, their teacher orchestrates a bonding between Jonathan and Shane in the hopes of helping Shane. While both boys are reluctant, their friendship develops into something very important to them both, but not without costs.
Carrie enters the picture when they are all older and coming to terms with their sexuality, but this leads to Jonathan & Carrie "discovering" an insurmountable obstacle to their relationship. Carrie is sympathetic and still cares about Jonathan. Nonetheless she then turns her romantic attention to Shane who does reciprocate her feelings, but both fear alienating Jonathan who Shane continues to love as a best friend.
The chemistry between these three becomes an increasingly difficult mixture of love, resentment, respect, caring, jealousy and misunderstanding.
They each want to maintain the innocent and platonic relationships formed during the summer of their youth, but their sexual maturity and natural desire to pair off in more intimate relationships makes the rite of passage a painful and, as far as the movie is concerned, an unresolved one.
Very well done. The actors made their characters very believable and their plight was emotionally touching & moving.
