AVP2 did not pull its punches like Alien & Aliens did which still attempted to be a family movie series despite its horror genre.

In AVP2 the Newt/marine you attempt to rescue fucking dies
In AVP2 the cat fucking dies eaten by the chestburster.
In AVP2 the entire pods section with humans still alive in it gets nuked from orbit
In AVP2 the Predator wins against the human.
In AVP2 Cortana dies by nuking herself and the pods.

Basically 180 degrees from the movies.
