“Summer Of ’84” (*** out of four) was a stirring melodrama set in the 1984 summer in which a group of kids (Graham Verchere, Judah Lewis, Caleb Emery, and Cory Gruter-Andrew) begin to suspect that their police officer neighbor (Rich Sommer) is a murderer and they attempt to snoop and gather information on him which brings them increasingly closer to danger and adulthood than they imagined. Cross-pollination of “Stand By Me” and “Disturbia” is well-observed and engrossing. Most importantly, all of the kids are very likeable and have terrific chemistry and camaraderie together.
