It's fairly true to the book but has necessary short cuts because the book (first in a trilogy) was a very dense spy thriller. Lawrence was much too chunky to be believable as a ballerina and then as the athletic agent she became. I think without some of the long mood shots, the film could have incorporated what really made Dominika special and a superior operative - she could see people in color, which told her if they were lying, dangerous, happy, etc. It would have been a visually great addition - but understandably time consuming to explain it. The very handsome Nate Nash - I don't get Joel Edgerton as that.
