I do not believe that the aliens look that bad, but if you think about it the aliens should not be in the "resurrection" style. In alien resurrection, the alien look was changed to fit the storyline, because when they were cloning ripley, the alien queen and her swapped alittle bit of dna. That is why ripley had the extra strength and the other extra-ordinary powers, that is also why the queen could give birth, and the generic alien design was changed to look "more human" than geiger's design, even if it doesn't. So since the aliens should have none of ripley's dna in alien vs. predator, they should look like the original gieger design, or at least like cameron's warror aliens. It's not a matter of how good they look, but how tey should look. p.s.- while stan winston's studio made the alien queen, the actual design was done by cameron.
