The Predator is a moderately entertaining but also disappointing entry in this series. Only fans of the Predator franchise or of Shane Black need to bother with this one.
Predators is a truer sequel to the original than the actual sequel, but it’s also not as good.
Predator 2 is a bad sequel to a pretty decent original film. Skip it.
Predator is a moderately entertaining action movie. If the creature interests you, then it might be worth your time.
