Lack of plot and character depth, huge lack of cultural accuracy, hiring big named actor to carry out the action, which reminds the only "satisfaction" and selling point while sticking to a shallow movie. If you want a movie with similar plot lines and scenery based on a real person, actual complex characters with layered acting, decent action and lots of intensity and good twists in the plot, I recommend another Netflix original "Close" with Noomi Rapace (The Girl with the Dragon Tattoo) and great supporting by Sophie Nélisse (The Book Thief). It's criminally underrated for one being a female action drama/thriller which people will always be nitpicking about opposite movies like this one starting out at a solid 7.4. What? That's higher rating than Die Hard 2 and almost the same as Skyfall. Not to get started on "6 Underground" coming in with 6.1 solid stars with its big names not even making up for the lack of so many quality-based things, putting an emphasis on "empty action and looks". Really gonna continue to do this, are we? Watch this one if you want decent action and with a big-named celebrity, not really caring about anything else. Then you'll be satisfied for sure.
