Anyone seen 'Raw Meat'?

Aka "Death Line". It's a 1973 British horror movie with the same premise, except set in the London subways, and was clear inspiration for this movie. "Raw Meat" is a lot more of a slowburn movie and develops the villains, but I think the parallels are unmistakable. "Creep" was also pretty clearly influenced by it. Anyway, really enjoyed this, it was fun despite the flaws. Good late night entertainment.
