I hate the thought of predators being portrayed as the "good guys". Taken under careful thought, they are actually more diabolical than the aliens. Aliens are natural born killers, & extreme hostility towards other organisms is in their nature. Preds on the other hand kill for sport & honour, they take pleasure in stripping the skin from their victims, & tearing the skulls from the bodies of their lifeless prey. There is no natural drive for this action, they do it for honour, & pure enjoyment.
The only idea that was ever given that the predators weren't completely monstrous killers spawned from the clan sparing Harrigan's life at the end of Predator 2. The main reason behind letting him survive was so he could be hunted again in the future. He was formidable prey, & to kill him while he was outnumbered, surrounded, & already exhausted & wounded from his previous battle would be a wasted opportunity for another hunt in the future. The elder passed him the antique 1715 pistol as a token of respect, as it would have taken a formidable warrior to topple a predator such as Harrigan did. For some strange reason, that basic showing of respect suddenly gave everyone the idea that predators could be "good guys". Then came AVP...& we all know what happened there as a result of Predator 2's ending being looked at in the wrong light.....
Anyway, rant over, lol. As far as AVP2 is concearned, I actually have a strange feeling that the aliens are going to end up walking away from this one in better shape than the preds. Although the fact that the preds in the next movie are supposed to be, according to Ian Whyte, veteran hunters, gives me some hope that they'll be able to take a far better fight to the aliens than Scar, Celtic or Chopper did in the first movie.
