I really think Predators, even though P.A. had them getting their asses handed to them during the entire movie, are
physically stronger then Aliens.
If you look at the movie, you really see that the Aliens get all their Predator ass-kicking glory because the Predators are distracted by somethig else.
Examples 1. Gill gets impaled becuase he's too preoccupied with Lex.
2. Celtic owns Grid during their entire fight, but loses when Grid pops out of the net Celtic should have known wouldnt have lasted long. So the dumbass shouldnt have acted like he had all the time in the world.
3. Scar gets tackled by an Alien becuase he doesn't notice one has sneaked up... right beside him? (Anyone else find this kind of f**king odd after seeing his shuriken disc scene?)
4. Scar gets his shoulder torn up when an Alien drops down from out of nowhere when he is watching Lex activate the sled. (Yeah, probably checking out her ass again.)
5. Finally, Scar gets imapled by the queen becuase once again his magical Alien sensing ability falls short and he finds that smiling at Lex when she yells "Got it!" is more important then the most dangerous opponent he had ever faced. (Seriously, did he really have to smile at her when she said that? Come on...
)
