Reviewing David Ayer's critically feted End of Watch, I complained that the film struggled to reconcile its "induced documentary" aesthetic with an increasingly contrived melodramatic narrative. No such problems beset this brutally ugly actioner, which opts to solve any and all structural issues by blowing things up, nailing bodies to ceilings, and splashing severed intestines around in ever-widening pools of blood. The plot is preposterous; a team of DEA agents with names that make them sound like a militarised version of the Spice Girls (Grinder, Monster, Pyro, Smoke) are double-crossed out of $10m, after which bodies start to pile up. Head of the pack is Arnold Schwarzenegger, whose acting has worsened with age to the point that it's now impossible to tell if his facial expressions represent angst, grief, joy, anger, sadness, confusion or orgasm. Mireille Enos provides a reason to watch as team bad girl Lizzy, but Olivia Williams struggles with the ludicrously hard-boiled dialogue, which reduces everyone to the level of crass caricature. Scenes of people kicking doors down and shooting each other in the head are efficiently handled – it's everything else that's a problem.
