After reading the synopsis and comments about this episode,"Hickory, Dickory, Doom" I thought it was going to be a really scary one.  What a disappoinment!  I thought it might get better after the mysterious man who hid his face that was watching the house rang the doorbell and demanded in a creepy, gravelly voice to see ,"The clock- I MUST see the clock!" and then barged in,opened up the grandfather clock and stepped inside and disappeared but it didn't.  It's an o.k. episode.  Inferior to one of the best ones, "Possessed by the Devil" which is excellent and scary.
