The soundtrack: I'd give it only half a point though for being absolutely unoriginal. Yeah, it's all great to hear the same eerie sounds from Aliens and the adrenaline pumping drums from Predator. However for me it worked backwards, since all it did was remind me the fantastic films this belongs to. Also, it's getting pretty tiresome to represent the soundtack as a homage seeing how the whole damn movie is a one big homage.
The Predator: I'd also give it only half a point, because while being better(better mask, overall more reminiscent of the original ones) than the ones in AvP(2004), it certainly had flaws(behaviour, the way it was represented in contrast with the aliens, some of the ridiculous weapons that belong strictly to comic book pages, etc.)
