Does anyone watch this show?  The latest episode was interesting - It was basically about a creature that feeds off the tears of others.  It found its victims at Grief Support Meetings.  (The episode is called "Mr. Sandman"). 

I enjoy this show generally, but found this latest episode a bit disturbing - especially the shots of women with tear-stained faces just before the creature "drank" their tears.  It's almost made me afraid to cry!
