Alien is actually a Quadrilogy, not a trilogy
but yes that one is my favourite franchise, besides Jurassic Park/World, and i also recently enjoyed watched all of the hunger games movies
if i gotta rank alien movies
1. Alien (first one is the best yep)
2. Aliens (good sequel, more alien action scenes, good acting, nice storytelling)
3. Alien Resurrection (especially loved Brad Dourif's role in this too)
4. Alien 3 (not bad but bit too much storytelling, took too long before any major alien action)
