This movie is a spoof of all those Rambo/Norris/Ahnuld commando bloodbath movies from the 80's. It is very unsubtle, full of cartoonish shootouts where the same bad guy terrorists get mowed down by the good guy plane crash survivors, some cheesy sex and boob scenes, with an original hard rock background music score. Basically, a random bunch of people crash on a Caribbean Island: punk rocker, Wall Street yuppie, hysterical woman, priest, etc etc; owned by Cuba. The island is a terrorist training camp for a motley bunch of cartoonish terrorists, loosely based on the 80's Communist types. There is a pig snouted redneck terrorist, a psycho Nazi Jew hating one, Russians, Arabs, a ninja, and even two Siamese twin leaders. They are going to land in the US and undermine us with AIDS and random violence, ala "Invasion USA", I guess. So this motley bunch of survivors, led by an ex Airborne Vietnam vet, start kicking some serious butt instead.
There isn't too much of a plot after that, but plenty of gratuitous violence on the level of Monty Python, with more shootout scenes than ten action movies put together. But the same bunch of terrorists keep getting mowed down by our heroes. It is funny yet the overkill grows on you after a while. But it definitely is chock full of special effects and weapons, especially for a low budget flick.
To call this a politically incorrect movie is a euphemism for a totally bad taste movie. But it does have it's charm, in a cheap, exploitative but not a stupid way. Definitely not for the weak at heart, while not gory compared to modern horror movies, it has some real bloody hamburger scenes
