Had a good concept but the execution was severely lacking. Seriously, the synopsis sounds great, and the opening scene sets you up for a ride, but then it all falls apart. It spends too much time with slow, stilted dialog and just a general snail pace. The biggest problem is it wants to be more epic, grander, wilder than it really is.
The main character, who is an impressive hulk of a man, lacks any charisma. His grungy voice and quips, I assume trying to harken back to bygone days of a "man's man" rogue, just didn't work. The other 2 women's characters weren't memorable, either. Not to bust on anyone's acting chops but this wasn't the movie where anybody shines.
The action was a real letdown, so those hoping for a banging good time with bullets flying and explosions will similarly be disappointed. There's minimal gunplay, with the usual "trained assassins/soldiers that can't hit the broad side of a barn" mindlessness, and the fisticuffs are even less impressive. For Stisen's stature, you'd expect him to be out there ripping people new ones but apparently, he's just an average joe when it comes to any physical combat.
Returning to the idea of it wanting to be bigger than it is, there are many over-the-top moments that feel ill-placed. In one scene, the heroes go down a fire escape while a bad guy rains not a hail, but a full-blown hurricane of bullets from a heavy machine gun at them for a good minute. I'm talking 1000+ rounds, and of course every bullet just ricochets off the railings, posing no threat. It's too ridiculous for this movie and feels like they couldn't commit to being too wild (most likely for budget reasons). The movie might've been better had they just gone nuts with it and not have it be such a serious affair.
