Plot hole: The way Naru defeats the Predator at the end is extremely contrived and unrealistic. For one, she figured out how the laser-guided bolt gun worked just by seeing the bolt follow the laser one time before. She somehow knew not only exactly where the Predator would be in the mud, but where he would stand and have the laser aimed exactly at his head. And somehow the laser turned on exactly when she needed it to. And also, the Predator had several seconds to duck once he realised. It should not work. (01:26:40)
Character mistake: The Predator is jumping through trees, then landing in a creek, splashing in the water. Its cloak barely flashes for a moment, then it can walk through the water still cloaked. This is a prequel to the other Predator movies, where it is already established that with their cloaking technology, even in the future, walking in water or getting wet disrupts the cloak and it malfunctions. (00:37:10)
Factual error: Early in the movie, the Predator is standing still while cloaked as an ant crawls across its leg. A rat grabs and eats the ant, then a snake strikes the rat. The snake starts to crawl away, then suddenly senses the Predator and gets startled, rattling its tail. However, rattlesnakes are pit vipers. They see heat. So even cloaked, the snake should have already seen the Predator standing there and known. Predator cloaks do not cloak from heat vision. (00:13:30)
Factual error: The movie is set in the Northern Great Plains of the United States, and the tribe is identified as Comanche, but the Comanche were located in the Southern Great Plains, across present-day northwestern Texas, eastern New Mexico, southeastern Colorado, southwestern Kansas, and western Oklahoma.
