I'm a huge fan of the Vince Flynn 'Mitch Rapp' series. If you're looking for a good action flick, then this is right up your alley. If you're hoping that it follows the book, then you'll be greatly disappointed. All in all, I liked the movie. But in my personal opinion, it could have been better if they followed the novel. Michael Keaton played a great Stan Hurley but the rest of the casting was off if you ask me. I still do recommend 'American Assassin' as a really good action flick.
