Tony Roberts, a portal to hell, a medium and an apocalyptic finale.  What's not to like?  "Hickory, Dickory, Doom" is fun from beginning to end (if you can call the end of the world fun).  The dark ending lingers in the mind.  What happened next?  Nothing good apparently.  This episode is firmly planted in my Top Ten.  It would be interesting to see a list of CBSRMT shows that deal with objects linked to the supernatural, including rings, paintings, etc.
