The reason the "0 casualties" was emphasized was because he was following John Connor's orders to not kill people (including the police) who were not the bad guys. There was no reason for him to go on an indiscriminate murder spree to eliminate a threat -- there was only 1 threat and he shot the shit out of it every chance he got.

Sarah Connor is also shown to be kind of a man-hating lunatic (particularly in the extended cut of her assassination attempt).

Also, Aliens was just the typical horror formula: everyone but the main character dies. Except in this case, a few others were allowed to live. Bishop helps her escape, Hicks helps her escape, and Newt is saved because she's innocent. Ripley also has to repeatedly face her fears and show personal growth (aided by male characters) to get through the movie. There's no indication that Vasquez is a lesbian and she ends up dying with Gorman in his redemption. Hudson gets a redemption. Sgt. Apone is shown to be a competent, reliable, leader. It's a very masculine storyline where multiple characters experience believable growth arcs.

I've never seen Titanic or anything after it.
