wait. what? (spoilers)
They kept referring to 1971 and 1982, but they don't explain. The one guy lost fingers those years, but how does that relate to the creature breeding? If it's "mating" every year, then why is there only one? And why did the guy chop his daughter's feet off? The other girls kept their feet. And who was the woman at the beginning? And why does a half man/half alligator have 2 mouths, like Alien???
