How this movie became a classic still baffles me

Rating: 1/10 (13 July 2016)

Seriously, what is the big deal of this movie? Predator is overall a mediocre film. The dialogue was stupid, like "I ain't got time to bleed" and "slack jawed f@ggets!" The action scenes were boring. This movie is hardly an action film. Most of the action in this movie comes from the scene where Arnold's team shoots up a military camp and when the Predator creature gets into a hand to hand combat with Arnold. The movie builds little suspense and I did not care for any of these characters. The movie tried too hard to be "cool" so I couldn't take this movie seriously.
Right before the showdown between Arnold and the Predator, Arnold jumps into a lake and when he got to the surface, he sees that the Predator also jumped into the lake. Arnold crawls away and as he does, his body is covered in mud. What baffles me is the fact that his ENTIRE body was covered in mud just by crawling in the mud as if someone got mud in their hands and smeared it all over Arnold's body. The Predator couldn't see Arnold's body heat due to the fact that his body was covered in mud. Wow. For an "advanced alien hunter" the Predator wasn't very good. It got fooled by a guy covered in mud. And does that even work? Covering yourself in mud hides your body heat? That idea is stupid. The Predator's heat vision was terrible. I could barely see anything when the camera turned to the Predator's heat vision.
At the showdown between Arnold and the Predator, the Predator was just slapping Arnold around like how any man could. I find it hard to believe how the Predator was able to rip Billy's spine out with its bare hands and lift and throw Arnold in the air with one hand yet Arnold was fine after being slapped in the face by the Predator. When Arnold finally defeated the Predator, the Predator set off its nuke and laughed exactly like how Billy did earlier. That scene was ridiculous. What was the point in that Predator nuking itself?
One more thing that did not make sense about this film, after Arnold's team shot up the military camp and took off, the Predator showed up and held a dead scorpion in its hand. You could see the dead scorpion in the Predator's heat vision. Umm bugs are cold blooded, they don't give off body heat.
The movie is overrated. I can see why this movie received polarizing reviews when it was recently released. How did this movie become a classic? I don't know. Probably because of the whole Alien/Predator crossover.
One thing is for sure, the ONLY reason why Predators are this popular is Xenomorph. If 20th Century Fox never wanted to make an AvP movie, Predators would had never become this popular.
