I loved Bateman’s direction of those two episodes. He does some stuff that could be called gimmicky, but for me it worked.
Unlike others, I’m liking Mendelssohn’s performance, though I do see the point about King’s cliché-fighting characterization being ignored in that casting. All the acting has been excellent so for, in my view.
My main issue is that, as mentioned already, there is a supernatural solution for the central mystery. I’ve often liked King’s work but am not the biggest fan of this type of device.
I’d also say that the central mystery of the ten (?) episode-story has been solved in episode 2. I haven’t read the book and know nothing about its plot, but my guess is:
[SPOILER]The reason that Bateman’s character had a double who committed the murder, framing him, is that Bateman happened to go visit his dementia-suffering father at the father’s nursing home and stumbled into the supernatural villain, who was offended and decided to get revenge. The supernatural villain was working in a home for violence-prone sufferers from dementia, because the villain feeds on emotional pain and misery, and there’s plenty of that in such a home. But Bateman’s character stumbled into the villain, so the villain took a blood sample and thus was able to duplicate the character’s appearance, fingerprints, and DNA. The villain then stole a van from an area the Bateman character had been staying in, to further the frame.
The villain is now hanging around the Bateman character’s hometown, soaking up the pain and causing more via influencing other people to do violence while they try to cope with the original murder. This influencing campaign includes the younger daughter of the Bateman character, who the villain intends to harm or influence to do harm to others.
So the autism-spectrum detective will be brought in and will figure out this is a supernatural villain, and won’t be believed, but will find an autism-spectrum way to defeat the villain, maybe. [/SPOILER]
This could be all wrong, but if it’s right, it’s a flaw in the production that nearly everything you’d want to know is spelled out so early in the miniseries.
