Aliens, the most idiotic monster there is, after all the aliens movies i watched, i can't find a reason why they kill, its not an animal acting instinctively, like to eat or protect their younglings, its not an intelligent entity killing for a clear reason like the predators who kill for sport, aliens are just boring predictable bullshit, sometimes the 3 inches 'insects' are smarter than people and the 8 feet alien is dumber than a rock, what a load of nonsense to put this story together and still it has so many holes
