Stalker in my opinion both are very cool in their ways but actually I prefer Wolf too.

The biggest problem here, and we discussed this in another topic. Paul Anderson clearly wanted the aliens to come out as the better species, he even admitted that he had a total bais towards aliens. With the director already leaning to one side, you can't help but get a bunch of overly weak predators. To off set this, AVPR made the wolf predator overly powerful.

It ends up being poorly directed movies by poor directors.

I think Wolf was better. I agree with Stalker as well, Scar teaming up with Lex was stupid because it doesn't make much sense. A predator would obviously not side with a human, especially after they infiltrated their sacred temple.

Agreed, A predator teaming up with a human is like a lion teaming up with a house cat. If scar really needed her help then he is obviously incredible weak.
