I remember that the Return of the Living Dead movies were great back in the day. Then I rented the third movie for my siblings and it was way different from the first two. If I remember correctly a young woman gets the zombie infection and works out if she inflicts pain on herself she kinda keeps her humanity. I think by the end of the movie she's like a human porcupine with metal sticking out of her body everywhere. I think that's how it went anyway. Probably fudging a lot.
