Members of an elite but ethically questionable DEA undercover unit made up of tough-guy clichés (played by overqualified actors and headed by Arnold Schwarzenegger) are being killed off in a variety of cinematically grisly ways. This sloppy, ultraviolent whodunit from David Ayer (End of Watch) is so pointlessly gory I call it “action torture porn.”

Though it’s Schwa-chan’s most “serious” performance in recent memory, the film, which is not without its scuzzy merits, might have worked better with a less iconic has-been. There’s a difference between intriguing plot twists and just being jacked around. (109 min)
