“Wet Hot American Summer”: Back in the summer of 2001, apparently no one was clamoring for a parody of 2-decade-old summer camp films, a brief genre that flowered and then quickly died in the late 1970s and early ’80s (“Meatballs,” “Little Darlings,” etc.). Created by members of MTV’s sketch comedy group the State, the film featured, among others, Janeane Garofalo, David Hyde Pierce, Molly Shannon, Paul Rudd, Elizabeth Banks, Bradley Cooper and Amy Poehler. It bombed with critics and at the box office, but guess what? Not only has it become a cult classic, but it has inspired a new Netflix original series, which becomes available on Friday, July 31.
