I went into watching 2 Guns not knowing what to expect but ended up having a good time. It's not the cleverest or most intense action movie out there, but it was fun and well paced for the most part. Sure it's basically a buddy cop movie with a bit of a twist, but an entertaining one even if it borrows pieces we've seen many times before for it's blueprint.
What it lacks in originality it makes up for in execution. Not much more to say than it was fun, and that's enough for this one.
