A great movie but with a normal ending

Rating: 6/10 (11 June 2017)

The technique of the story telling, the photography and everything is great. The way it unwrapping the mystery and make audience keep questioning the situation is very nice.
But I have to say when the moment the real bad guys shows up, it ruined the genius of this movie. Feel like free fall from one of the top mystery story into a routine apocalypse story ending...
Worth watching for sure. I'd gladly give it a 6.5. Just a little shy from getting a 7.
