In spite of poor ratings I simply took a chance at watching this Idris Elba movie. Surprise! Surprise! Then I realised why the movie got low ratings. No Werewolves. No Zombies. No sex. No Blood and gore. No bogus action where the hero is absolutely untouched by 3 - 4 guys shooting at him from 20 - 25 feet with assault rifles. Believe me I could do better. These are the typical requirements of the American viewers. Absolutely and totally plausible and believable. Richard Madden also turned out to be familiar face for me. I really wonder if the others here who rated it low really understood what was going on! May be they left their brains home before entering the cinema house. Matt Damon sucks big time compared to Idris Elba. Overall a very watchable movie.
