Best horror movie franchises of all time

The first installment of the "Insidious" film franchise was released in 2010. Starring Patrick Wilson and Rose Byrne, "Insidious" follows a couple who, while coping with their son's sudden comatose state, realize that he's being used as a vessel for demonic creatures. The success of the first movie spawned three more films: 2013's "Insidious Chapter 2," 2015's "Insidious: Chapter 3" and 2018's "Insidious: The Last Key." Together, all four have earned $539 million at the global box office against a total budget of $26.5 million.
