“Hot Summer Nights” (**1/2 out of four) was an endearing coming-of-age story as a teenager (Timothee Chalamet) spends his summer in Cape Cod where he encounters his first experiences with girls, drugs, and wild times. Offbeat story is told with an engaging sense of humor and is nicely and gently directed by writer-director Elijah Bynum in his debut but is marred by unnecessary unpleasantness in its final third. Still worthwhile though for fans of coming-of-age stories such as “Stand By Me” and “The Spectacular Now.”
