I wholeheartedly agree with the Black Biped's sentiments. (Though you must mean Alien 5 should be set on earth, as Alien Resurrection=Alien 4) And I can't comment on AVP, having not seen it.

As for the man-in-a-suit issue, what else could it be? And why is that bad? It's a darn good suit, and it never occurred to me to complain about the fact that there was a man in it.

It seems it might be time for me to watch these movies again myself.
