maybe a number of the actors would all have physiques where they looked as if they were competing for muscle size with Arnold Schwarzenegger, but I'm sure that McTiernen would have had an interesting new alien monster. he knows a great and a rubbish alien monster when he sees one, and we wouldn't have been complaining about lack of fun personailities in the characters, and well these last two points are major concerns. Whether it would have been better than Cameron's movie is not for me to know, but Cameron but more input over the design aspect. McTiernen didn't know what his Predator would look like until he received it and said "no way!", but one thing about McTiernen, he had enough of a solid standing point to have another alien monster, and in the end Stan Winston who provided the monsters for Aliens turned out with the alien creature for Predator. But, I didn't like Winston's own designs sketches for an alien queen, they looked all wrong
