She Devil - 1957 - 5/10

You do love me, don’t you Dan?
Yes, I have killed a couple of people, but so what.
I want what I want, and that includes you.

Kyra had been near death, incurable, until the doctors tried an experimental, insect based serum on her.
Now, she heals immediately, even from fatal accidents.
Worse, she has lost her humanity, empathy, and is moving up the predator food chain.
Straight instead of campy. Not enough SciFi, nor enough Horror, not enough murders!
Mari Blanchard a real force as the driven fatale, while menfolk are roadkill.
