I wonder how Eva planned on killing Don?
Don wasn't a fragile old man that could be spooked into a heart attack, or scared off of a bridge.
The ghost could scream and look rotten. Big deal.
Don't get me wrong, I really like Ghost Story. I saw it in the theater back in '81. But even then, as the final scene was unfolding, I was thinking "okay, this is indeed scary... but what's she gonna do?"
