Imagine a movie that throws every racist black joke cliche you could ever think about into an 88 minute movie. Then imagine that it is recycled every few minutes. National Security is a comedy that is not only unfunny, but is also unoriginal, full with cliches, and downright pointless.
The movie centers around Earl Montgomery (Martin Lawrence), a security officer, and Hank Rafferty (Steve Zahn) an ex-police officer who turns security officer after what seems to be a phony Rodney King type beating. Now, this is where the movie starts to go wrong. It takes the typical black/white man stereotype and turns it into a cop movie that dares to enter where no one has gone before- make consistent black jokes from a black guy. Don't get me wrong, I'm not using black in a derogatory way, but merely to point out that these "African-American" or so called black jokes are unfunny and dull.
Later, the two somehow stumble upon a plot to take a precious metal-alloy that will make a crooked cop and some other thiefs rich. By coincidence, this group is also responsible for Hank's partners death. Because of this, Hank goes to revenge his partner.
This movie could have been replaced with stick figures and I would have been just as delighted.
