Xtro feels like it would've fit better in the exploitive 70's. There's definitely a sense of misogyny, as the women are all relegated to birthing vessels for the aliens, thus their fates appear to be much MUCH worse than any of the men's. The final scene pretty much drives the mean-spiritedness home, too. That said, for what it is, it's never boring. Its pace is surprisingly brisk. Where it lacks in story (and boy does it lack), it makes up with weirdness and WTF'ery. It also references pretty much every alien movie of its era, especially Alien. 6/10
