2 Guns tells the complex, at times convoluted story, of two drug dealers who both happen to be undercover law enforcement agents, who don't realize that the other is law enforcement. Okay, you still with me, because the movie only gets crazier from here on out, but if you can keep up with that, then you'll like 2 Guns.
What really makes this movie work is the chemistry between Washington and Wahlberg. They're funny together, and they really make would could have been a standard, run-of-the-mill action flick worth watching at least once. It's fun about 75% of the time, and its thanks to its two leads, however, the plot is nothing new and it definitely is not engaging enough to keep your interest piqued, so do expect yourself to almost zone out a few times here and there.
Ultimately, if you enjoy a fun, breezy movie that is violent and filled with expletives, 2 Guns will more than satisfy, just don't go looking for too much more.
I give 2 Guns a B-!
