FLIMSY PREMISE, ILLOGICAL ENDING, BUT WITH FUN MOMENTS

Rating: Null/10 (13 August 2004)

(WARNING: MIGHT CONTAINS SPOILERS)
My one-line summary says it all!
I'm sorry, but the premise of this film is just too weak. Also, while it had some fun moments, the filmmakers seeemd to disregard significant precedents set by the first two "ALIEN" films (1979 and 1986) and "PREDATOR" (1987). This is most notable at the end, when the infant Alien bursts from the Predator's chest without its egg having been implanted by a Facehugger beforehand. In case someone wants to argue the Predator was infected by the Queen Alien, how could this have happened? Why this important step in the gestation process of an Alien was skipped defies credibility. However, it definitely set the stage (so to speak) for a sequel.
As for the premise, are we really supposed to believe that a pyramid lay beneath the Earth's surface for such a long time and was not discovered for so many years? Given the ritual of three Predators flying to Earth every 100 years to battle such a multidue of Aliens, are we also supposed to believe that only THREE Predators successfully battled so many Aliens until they were finally defeated (their prowess at such battles notwithstanding)?
Why didn't the filmmakers keep things simple? It would have been so much more credible had the Predators simply flown to a planet already inhabited by Aliens. Another solid premise would have been that the Predator species declares war on the Alien species and attacks their planet. I realize this film was based on a comic book series, but come on, people, couldn't the filmmakers have put just a little extra thought into the storyline? Had someone devised a solid premise, even the humans wouldn't have been necessary. The film could have featured just the Aliens and Predators and been damned entertaining.
Oh, well!
Despite thrilling special effects and good battle sequences, at the end of it all, this film really isn't worthy of being grouped with its aforementioned predecessors.
