The problem is, I feel, people were automatically comparing these mini features to The Thing, Re Animator, Phantasm, AWIL etc etc...which is a little unfair. It always been promoted as "flims made by the people that bought you..." The Thing rather than "films just like" The Thing, remember.
They were never going to be like that, because the natural constaints of TV make it a much more cerebral and idea oriented beast. You have to think outside of the box (oxymoronically, in this case).
Of course it's not going to feel like Carpenter's panavision-shot, measured and personal spook stories. But it still has its own strengths.
I thought Drew and Scott's screenplay for ...Burns, though similarly constrained by the pure sped up pacing of TV, was a terrific piece of genre gruesomeness (nods to other material included, before anyone mentions them). The script was still tight and textbook.
Likewise Gordon's gim entry was a terrifically memorable and atmospheric piece of fiction. Disturbing as great gothic fiction.
Had these been episodes of any other television show they wouuld have been treated with far less skepticism, I think.
It's a little like complaining Chuck Palanhuik's latest haiku just doesn't have the depth of Survivor. Different mediums.
