Bull-to-the-fucking-shit that a psychologist wouldn't be able to tell that someone they're married to has a severe personality disorder, especially when his colleagues could easily detect it. Even if she did manage to lie to herself during the marriage, she wouldn't have genuinely questioned it when it became clear that she couldn't trust him.
He does this big tv interview saying he loved his dead mistress and that he thinks he knows who did it, and it's this huge episode ending cliffhanger and then...nothing? She doesn't even react to him talking about being passionately in love with this other woman?? No reaction, it's not even addressed.
Why the hell didn't she immediately put her kid in therapy? She keeps saying she's doing all of this inscrutable nonsense for her kid, so why wouldn't a therapist know that her poor, emotionally mangled kid would need immediate psychological support?
Let's not even touch on her own therapy techniques...
Who was the other woman he had an affair with? They cut the scene right before he gave the lawyer her name, so I kept waiting for that ball to drop, because the only reason to cut away from revealing her name is if we know who she is. I spent the whole time convinced that it was the overly dedicated best friend who he turned to for legal help. That would have been a great twist.
Nope! Instead she's just super conveniently buddies with the prosecution. I hate lazy, convenient writing.
Lastly, I will say one good thing, Hugh Grant can sometimes really act. There was that one scene where he tells Kidman about his sister dying and he's all emotional about it, and I turned to DH and said "either Hugh Grant can't act this scene well or he's acting the shit out of it and his character is supposed to be almost convincingly faking emotion"
I could believe either scenario because he's often dropped the acting ball, but he also has brilliant moments, and it was obviously plausible that the character was faking his grief, but most actors aren't great at faking someone faking emotion.
I was happy when it turned out to be the latter and I could really appreciate Grant's execution of that scene. He's a notorious ass though, so perhaps he has a lot of personal experience with faking emotions, so understands the nuance of it?
Overall, I felt the show couldn't really decide what it wanted to be. It was perpetually stuck between trying to be a character study about Kidman's character and a whodunit murder mystery with pulpy cliffhangers, even implying that she might have done it.
It tried to be too many things and in doing so failed to execute any one thing properly.
