Number 443 on the top 1000 films of all time is the action-thriller Predator
Dutch (Arnold Schwarzenegger) leads a group of elite commandos as they attempt to rescue hostages from guerillas in the Central American rainforest. His group consists of mercenary Mac (Bill Duke,) explosives expert Poncho (Richard Chaves,) macho Blain (Jesse Ventura,) tracker Billy (Sonny Landham,) Dutch's commander Dillon (Carl Weathers) and wisecracking smart ass Hawkins (Shane Black.)
If you were to measure this film by an action-film standard, then it ticks every box in spades. You have the tough-as-nails soldiers, cheesy one-liners, undeveloped female characters, gunfire, explosions and Arnold Schwarzenegger. By that metric, Predator is a great film.
By any other metric, it is a load of rubbish. Of course it isn't pretending to be anything other than your average shoot-em-up, but shoot-em-ups can still make you care about their characters. Shoot-em-ups can still be entertaining.
I would say that the characterisations of Dutch and his men were paper-thin, but that's being generous. They were non-existent. They were nothing but your generic wise-cracking, vulgar soldiers. The only civillian and female character - the guerilla Anna (Elpidia Carillo) was similarly under-developed. At first it seems like she only speaks Spanish until she can suddenly speak fluent English. Why the change? Reasons.
The soldiers also didn't act like soldiers. They were so unrealistic from the whole group blindly following a million rounds into the jungle in an effort to kill the predator, to Dillon and Mac running off on their own to kill the predator, to Billy throwing down his gun to fight the predator with just a knife. Surprise surprise, he dies quickly. It just seemed like stupid characters doing stupid things for no reason but to advance the plot. If this were teenagers running away from Jason Vorhees, I'd get it, but fully-trained marines? Come on.
If you're going to watch Predator then manage your expectations. If you are expecting ground-breaking cinema, or at least entertaining cinema, you will be disappointed. But if you are after a popcorn-munching, octane-thriller, then Predator is the film for you.
