This is one of season's 12 best episodes in large part because it could be readily inserted into seasons 1-5 with only a few relative minor elements edited out, i.e. Switch Ketch to Bobby, remove references to Mary, and the episode plays fine within the earlier seasons. It is a monster of the week episode and it provides a nice break from the tedium of this season's storyline. The script is good enough-it's a mixture of The Benders and any number of the pagan god episodes- that it would hold its own against most of the very good episodes of the early years. It isn't among the best episodes of the show but it is a fun compelling short horror film with just enough blood to be unnerving and enough gags to be funny.
Best of all Sgriccia's technical direction is exceptionally tight and it is the most unnerving episode in several years. The show became much more of a melodrama and fantasia as the years went on but every once in awhile the creators remembered that this show was meant to be a horror anthology. Exhibit #1.
