As a fan of Italian horror you watch a lot of strange shit, but this is one of the weirdest. Not because of its plot, just because of how it switches between being inept and amazing.
Mainly the amazing bits are "Oliver Onions"'s prog-rock score (and i hate prog-rock), but there are other things too. Like, for example, the green lens flare that highlights one woman's eyes as she delivers a crucial line. That can't be accidental.
And then there's the gore too: the build-up to the reveal of the alien goes on for so fucking long it's like it's trying to send you to sleep. But if you snooze, you lose, and what you lose out on is an incredible face-breaking alien birth scene.
I mean, its total shit, yet on my second viewing I already feel addicted to Alien 2, and I'm sure I'll be watching it again and again.
