The performance of the actress who portrayed the evil sister elevated this show's quality. Favorite line (quoting from memory) "This place gives me the heebie jeebies. Let's go back before he let's loose those damn dogs." Early in the episode I assumed the husband was the Bad Guy, so I was pleasantly surprised when the sister was revealed as the villain. And her strange, almost romantic attachment, to her brother jumped out at me. RMT was not afraid of dealing with themes/stories that could be considered controversial.
