10. Wet Hot American Summer: First Day of Camp
Wet Hot American Summer is a 2001 movie set in a summer camp in Maine that flopped on release but has gathered a cult following over the years. So much so that its creators made an eight-episode prequel series reuniting the entire cast including Janeane Garofalo, Amy Poehler, Bradley Cooper, Elizabeth Banks and Paul Rudd. Middle-aged adults playing teens is just a tiny indication of how wonderfully weird the show is.
