I say action, because the story already isn't perfect, it could be better, so the best we can hope for is that it is executed as good as possible, and it looks that way, but still, the earth present day keeps the story from being 100% perfect, the creature effects are important, but there have never really been creature effects for these creatures that are down right unbelievably terrible for the time they were made in, yes, AVP got the pred look wrong, but the only real bad part was the realisticness of the face, the bodies and whatnot looked good, but were just done in a style most didn't like.
and I like the predators face, it looks good, and again, its not a great picture to judge from, I mean, compare what most people thought of the alien from that first released pic to what they think of what they saw in the trailer, and the opinions of the two are usually very different.
but for a film like this, where these creatures really aren't scary anymore, the horror isn't the most important aspect either.
So I say action, and that includes fights and deaths all around, any scenes of intensity count as action for me, anywhere where the creatures are attacking, and the humans running in fright, all falls into the action of the film, and if that is done in a really really great way, I think the film will at least be quite enjoyable
so there really isn't any one most important aspect, but if there was one that I want them to nail in comparison to the last film, it certainly would be the action.
