It had many of the HORROR element.

Such as:

A. HORROR ( of course )
B. Scary
C. Intrigue
D. Aliens ( REAL scary )
E. Mystery Characters

Support HORROR as it broadens its genre acceptance criteria and lets in the outskirt shows who have to be lumped in with pissy things such as HORRO/SCI FI, SC FI/Mystery. Who the hell says, my favortie shows are HORROR/Sci Fi ??

ITS HORROR.
