A sci-fi-like, cataclysmic story similar to “Blindness” (2008) and “Contagion” is “Perfect Sense,” only it doesn’t make perfect sense. The bizarre Doomsday happenings play out in Scotland where an unexplained malady causes people to lose their sense of smell. What could follow is the loss of all the senses (taste, touch, sight and sound). Within the frightening events is a blossoming love story which may be short-lived of two single people with shortcomings. Ewan McGregor’s Michael is a chef in Glasgow, an irresponsible, self-centered ladies’ man. The handsome philanderer meets a prospective soul mate in Susan (Eva Green), a loveless, embittered scientist. She’s investigating the burgeoning, global epidemic of afflicted people not only losing the sense of smell, but their escalating fears of losing it all, as many desperate to survive behave like wild savages. Scottish filmmaker David Mackenzie’s cautionary tale elicits moving performances from the leads with background music heightening the on-screen happenings of terrifying events.
