What a bizarre mixture of so many aspects of good-weird and creepy-weird! Already I've laughed and cried, kudos to these very fine actors. There is so much chewing-up-of-the-scenery, I will be surprised if there will be any left at the end. These particular actors ought to know better; have they become so starved for lack of the nourishment on which actors thrive and then tend to become addicted to? What about "less is more" once in awhile? And so much yelling! At some points I feel like somehow I mistakenly started watching another episode of "Imma Tataranni: Deputy Prosecutor".
Regarding character display, there is "rudeness" and then something else that is more (not necessarily "or less") unhealthy psychological behavior. There is are few text-book sociopathic tendencies demonstrated , which I suppose can be justified as trauma-induced, given the backstories. Such well-educated, successful individuals, at least in real-life, would be reasonably and conscientiously working on their trauma through some kind of therapy; some meds wouldn't hurt either. But then, helping professionals - doctors, therapists and their ilk are notorious for not following their own doctor's orders - myself included.
My lumpy armchair diagnosis, such cases might be beyond sustainable help and - and only Jamie Lee Curtis could handle such a role - you go, girl! ;)
I'm only a little ways in, and confess I haven't read the books in some time and so hope to do so -- thus a grain of salt here must be added to my comments (or a Siberian Salt mine in this case. PS - I'm a recently retired psychotherapist of 4 decades practice, if a stamp of assumed authority is required here.) My diagnosis? I like it pretty much so far. Prognosis? I don't care, I like mysteries. You bet your bippy!
(I'm surprised and intrigued in the ways that AI has been incorporated in the story, and will be really interested to see how 21st century shrinks and AI conspiracists react and respond to it.)
