Upon hearing the title The Cramps: A Period Piece, one can expect a film with its tongue firmly planted within its cheek. What can also be expected from writer/director Brooke Cellars’ quirky indie horror gem is sincerity, laughs, and an immaculate 1960s aesthetic. Influenced by the works of John Waters, Mario Bava, and Frederico Fellini, The Cramps puts a campy horror spin on endometriosis, a medical issue that many women deal with, and does so with a lot of heart.
