Decent action movie, no real plot hook, and no major protagonist moral compass attractant. I would have rathered the screenplay writers stuck closer to the book (like making Courts' awesome book dad a jerk in the movie). Netflix should have made an 8-12 episode series out of it, like Amazon did with the recent Jack Ryan. Jack Ryan is a MUCH better watch. Gray Man is a MUCH better read. I feel bad for Mark Greaney.
