Why all the high ratings!

Rating: 1/10 (15 November 2014)

This was recommended to me for a second time, so decided it must be good. I was told "One of the best films I've seen!"
After watching i checked the rating on IMDb (7.9 at the time)to find its loved my many others too..... what am i missing?
There is nothing about this film i like. The acting is poor, the scenery/locations are poor and the story is woeful. It reminded me of the really bad low budget films, done my Channel 4 in the UK a couple of decades ago.
The story doesn't answer the questions the viewer has, like why people stopped having babies, why no immigrants, all the gangs and why people are having to hide. Also why nobody questions a girl in child labour screaming and grunting through security check points. Why a man managed to bump start a car in wet mud on his own and still out run bad guys only a few feet behind him!
60 minutes in my wife said "This is pathetic!" and went up to bed. I should have done the same.
