Hero
I like Aliens. But the first is such a great movie. A nice slow burn. A tight cast that you get to know before things get horrible. If you walk into it blind, there's some great twists and you really don't know who the "hero" is. There's some great moments of tension and horror and a lot of world building done with very little. It's a nice, tight movie that really stands on its own.
