Hands down it will have to be Alien 1. When you first watch a slimy, worm-like creature bursting out of someone’s chest at the tender age of 8 when I was but a wee little girl, and then it turns into a freak with acid blood, well, it tends to leave an impact on young minds. Though I must admit, I didn’t really care much for the humans at that age, I was just worried if the cat was going to be ok.
On the yautja side: Predator 2. Bad-ass in a can. Blood and guts and gore throughout the entire movie. I think there was some dialogue in there, but if there was then I wasn’t paying attention to it. Unlike its predecessor, Predator 1, Predator 2 gave the yautja generous screen time…and without the mask too. And it wasn’t located in the jungle where there was safety in the forest, it was on our turf! The concrete jungle in all its heat-wave sweaty glory!
