the very first one was huge on symbolism, maybe not of the religious kind, but yeah the two latest were convoluted as hellI suppose Fassbender was one of the few good things about Prometheus so it made sense to him. The Alien story has limitations, they should have stopped after Aliens. Scott decided it was limitless and needed robots, heavy handed religious symbolism and every ounce of mystery sucked out of it. Beats me, too
