***SPOILERS***
Sorry - but the Aliens kick the **** out the Preds pound for pound. A single alien waxes two preds in the first fight scene.
Of course, the last pred nukes the 'hive' and kills all the aliens except for the queen, who comes back and kills the last pred before the human kills her Lt. Ripley style.
If youve seen the movies, there are plenty of little nuances that liken to the other films.
For example, there is a short sequence where Mr. (forgot first name) Bishop Weyland, CEO of Weyland Corp, is seen at his desk shuffing through paperwork - visitor somes in and he takes his letter opener and briefly runs it betwen his fingers a few times ala the andriod version of himself.
Couple other odds and ends.
Go see it if you want to be entertained for 90 minutes.
