Life-long franchise fan, long-time reader, first-time poster.
I'm a twenty-seven year old who first discovered the Alien films via an unusual route - I was into H.R. Giger first as a young teen, and learned about this film series based in part on his artwork. I was immediately floored when I watched Alien for the first time, because while I'd been familiar with the film's title and place in pop culture before I first saw it, I hadn't realized the sheer artistry that went into making the picture, or the levels of subtext in the story.
This movie was a perfect representation of Tiger's work in Necrom IV.
I might be one of a handful of fans to really not like Aliens very much; I felt like the imposition of an overt insectoid lifecycle on the creatures stripped them of much of their majesty and power. Conversely, I love Alien 3, and I think that the religious symbolism of the picture nicely echoes the carnal spirituality of Giger's creations (recall that the creatures in Necrom IV appear to be engaged in some sort of ritualistic sexual activity). The less said about Resurrection and the AvP pictures, the better. I thoroughly enjoyed Prometheus, warts and all.
I'm extremely hyped for Covenant and anti-hyped for Blomkamp's fan-service Aliens II.
That's about it, I suppose.
