'National Security' isn't terribly adrift from being a standard Martin Lawrence flick, which would be a compliment as he is an actor I've mildly enjoyed in said sorta roles down the years. This one just doesn't work, which is a shame as I also like co-star Steve Zahn in other films too. Zahn feels miscast, Lawrence is the one that stops this from truly falling through the floor. There are good jokes in there, albeit via the overly relied upon race humour, and it features some solid practical effects/stunts. I just never really got into it, nor did I sense that the leads were a satisfactory match for each other.
