Great film, if a bit flawed:

Rating: 8/10 (4 November 2010)

This original Predator # one is extraordinary, even in repeat viewing, for Arnold fans. Its sequels are OK, especially number two with Danny Glover but this one is the best. For first viewers it has a great, slow reveal to terror.
Two future state governors worked on this one and both are interesting to watch, both former athletes with large bodies.
The only two issue I had with this one is –
A) In one scene it shows Arnold going for his knife only to discover it has fallen out of his sheath somewhere, back perhaps during his two long falls into water. Later, we see that he has magically found it, somehow.
B) In the final scene, he has escaped the predator. The predator has set up what appears to be a nuclear explosion in attempt to destroy his adversary, who has dealt him a lethal dose of heavy timber. A helicopter shows up on the scene. Inn the middle of the jungle and after the explosion, the helicopter magically locates Arnold.
Giant gaps like this work against my suspension of disbelief. What also works against the grain is that something like that gruesome monster, a brutal hunter, has managed to create the technology for interstellar travel. It's akin to believing that a wild boar has accomplished rocket science and all of its ramifications.
