I don't reakon that AvP is unimaginative. Its quiet the opposite
If the aliens was faced off with any other sci-fi creature it wouldn't work at all, plus all your selections was just stupid, (which am sure you ment to do that). If AvP fans like myself want a stupid movie we will give you a call.
I am kinda pissed though that there won't be any Colonial Marines in AVP. It would have been wicked cool to see them just get caught in the middle of the war and see them have to adapt. But I guess 80's soldier bravado portrayals went away with Aliens, eh?
