Quoted from Stones:I think its crap they did made him a replicant. I read somewhere they were trying to show replicants were full of humanity....and the humans were basically drones..
I'll always think of him as human, makes the film better. I think if Aliens does well then will we see Predator from Heighway at some point and I for one want it based on both films, like Aliens choose which film you want to play, the 2nd is loaded with greatness for a pin, thinking of the clips and call outs from those films, oh man.
