The first Purge posited a relatively clever science fiction plot: For twelve hours every year all crime is legal. To work within its low budget, it confined most of that activity to one house, and it was slightly better than expected, but it didn’t seem to capitalize on the premise as well as it could. But its sequel The Purge: Anarchy takes that idea to the place it should have started: On the street. Following five people who are caught in the middle of purge night by either choice or accident, it does a much better job of exploring the possibilities of what might happen if for one night a year, all crime was legal. Frank Grillo stars in the film, and my review of the film’s Blu-ray follows after the jump.
