First thing you must know is that you'll blow out your speaker system trying to hear into what's going on in the movie. The sound mixing is so so bad, it's insane this movie cost $205mil to make.
Now, the story is not that dificult to understand, somewhat direct if you can hear what's happening. Whats bad is that there's no heart to our "protagonist" motivations. At all. The little drive we find behind characters actions we could care less about. The majority of the action scenes are super enjoyable but without our audience investment into what's happening they feel like just empty action scenes being thrown at you.
The worst act being the end fighting sequence; who are they shooting at? Why are they in this location & what is going on? Ultimately, you'll be left feeling like you've wasted your time, even while watching in the comfort of your own home.
