Aliens for me, everything about it is the kind of stuff I loved as a kid and still do and probably will for the rest of my life. Cool monsters, space marines fighting said monsters, futuristic weapons, robots/mecha (still don't know what to classify the PL
), and a squad of ultimate badasses, all mixed together to form the kind of movie I can watch over and over without getting tired of it. Not a lot of movies do that to me.
