I need to preface this by saying I had such high hopes for this show as I adore anthology series.
I don't care that Stephen King wrote "Gray Matter". King has written his share of clunkers ("Dreamcatcher" immediately springs to mind), so holding up his name is a bit of a crap shoot, This episode seemed rushed, and might have been better if expanded a bit. Jordy Verill meets The Thing. Adrienne Barbeau (John Carpenter's ex) doing rapid calculations on the spread of the "gray matter" was a nice touch, a call back to Blair's calculations in "The Thing".
"Head of the House" was just insipid. In the 70's there was an anthology series called "Circle of Fear" which featured a dollhouse episode, It starred Melvyn Douglas and Jodie Foster (I mention this for perspective). "Tales from the Darkside" also did a dollhouse episode. Seek those out instead.
"Bad Wolf Down" is one of the dumbest things I've ever seen and I once saw a Steven Segal movie. Props for naming a character "Quist" (The Howling"). Otherwise (insert your own extended raspberry here)... Sadly, this fart of a tale is attached to "The Finger".
And "The Finger" is awesome. I loved Bob. DJ Qualls did an amazing job. To say anything else would take the fun away.
"All Hallows Eve/The Man In The Suitcase" are both bad for their own idiotic reasons, and both come down to a lack of logic. It's clear why the one batch of kids doesn't age, but the others should be getting increasingly older. Possibly even grown up and married. As for the dude stuck in the suitcase, just cut him out. Cut the suitcase. The whole plot of this is based on everyone being idiots. I fully understand that they goal was to show whether one would do what's right vs. what benefits them personally, and that's a great little lesson. But for me it would have been vastly improved if just one person suggested the obvious--break the suitcase apart.
All that being said, I'll keep watching, and then likely skipping ahead, in hopes for another gem like "The Finger".
