Ex-governor of California Arnold Schwarzenegger turns up as a Drug Enforcement Administration (DEA) supervisor in the latest crime thriller directed by David Ayer, who wrote The Fast and the Furious (2001) and directed thriller-drama End of Watch (2012). Though the trailer is hardly likely to set your expectations too high for the classic action star’s return, this B-grade exhibition of blood, gore and clichés still manages to painfully disappoint.
