My guess is that they were really expecting another Hollywood spy movie with Jennifer Lawrence as that double-agent action heroine with plenty of action sequences, cars chases and enough of a plot to say it was a movie...I can see why they hated it, because this is not that film.

This is a smart, slow moving, back stabbing, violent, gory, cold-blooded character-driven spy thriller about a Prima Ballerina turned spy whose main talents are that she's intelligent, she's a survivalist, she has a temper but is capable of holding off for the longer chess match, and she's attractive.

If you find that intriguing, then ignore the BS 1 and 2 star ratings. They were just unhappy they didn't get the run of the mill spy action movie.
