I still buy DVD's so I'm currently awaiting a box with all four Alien movies. I have about 200+ DVD's
Cool. One of the great series from 80s. Aliens (Alien 2) is my favorite. It was more of an action-movie than it was a horror movie, but it had such a cool look to it, great action scenes, and eye-popping special effects.
And I really liked Alien 3. I know everyone else didn't. And it wasn't as good as Aliens, sure. But I thought it was a still a fine Alien movie. Very intense and claustrophobic feeling. (And it certainly wasn't as bad as Alien: Resurrection.)
Have you seen Prometheus? It's not an Alien movie, per se, but it is connected to the series and set in the same universe. More sci-fi than it is horror or action. But it's a good sci-fi movie, if you like sci-fi movies.
