Storm Reid and David Oyelowo make 'Don't Let Go' entertaining to watch, says critic

Our critics review "Official Secrets," about an intelligence specialist who leaks a memo that the U.S. is enlisting Britain's help in blackmailing U.N. members so they'd vote for invading Iraq;  "Spider in the Web," about an aging spy who's trying to redeem his life and career; "Don't Let Go," in which a detective gets a shocking phone call from his niece who was recently murdered.
