I saw the design of the Giger's monster as a kid and it always stuck with me because, well it's fairly interesting looking. Not just that but, the whole life cycle was fascinating to me, probably because I understood little of the subtext. Caught the movies on TV when I could, and played the games. Just thought "I can't wait what new interesting things hold for the future!" and nothing came. It all sort of just looks the same, there's not much to a monster movie anymore, which is fine but pretending its more than it is, is what I hate about modern "monster movie" Hollywood today, they're so focused on these photoshop concept monsters that when the script demands that we're supposed to take this as seriously as possible, there's really nothing there in the final product for me to care enough to finish it. I mean I'm sure there's a lot you can do with digital technology today to do something unique but there's a studio behind anyone at any given time poking your shoulder saying "You can't give the monster a penis for a head"
And where the fun is that anyways
I'm beating a dead horse a billion people have beaten before though. I just, love Alien because I understood it more and more as I grew up, and yet I'm still entranced by the forest of lights and detail the Nostromo has and its lived in look. Everything in the movie is just built for intoxication and design overload that it's hard not to fall in love with the movie.
I like predator a lot, but the whole setting of alien is so fascinating to me that I can't help to love it. The design Giger did for everything is just, so unmatched to this day. The crashed derelict, the biomechanical space jockey space suit, the planet, the costumes, the Nostromo and all its little details inside and out, how you can instantly forget these people are actors and not really pissed off beat up laborers who want to get home
All of it is just, charming. I don't know much my bias is effecting this and how much rose tinted glasses are coming into play, but I'm hardly the only one
