The Forever Purge is as diluted as one might expect of a franchise’s fifth and final installment. The title, of course, tips viewers off to the twist, which is that instead of the annual 12-hour event in which all crime is temporarily legal, this time, a group of people have decided the annual Purge should go on forever. Blunt and at times a bit boring, the film follows Adela (Ana de la Reguera) and her husband Juan (Tenoch Huerta), who live in Texas, where Juan works as a ranch hand for the affluent Tucker family. Eventually, the two families must band together to save themselves from a “diseased” America. While this may seem like the perfect setup for a nuanced social commentary on class divides, which some of the other films pull off to a varying degree, it, unfortunately, devolves into a collection of manageable metaphors and tepid takes.
