It explores the emotional effects of an extramarital relationship. Noah is a New York City schoolteacher and budding novelist with a wife of twenty years and four children. Alison is a young waitress and wife from Montauk at the end of Long Island, trying to piece her life back together in the wake of a tragedy.
It took me almost the full first episode to get the dynamic of the narrative (a bit slow, I know... ), as at the start I thought it was just another dramatic love story, but then... WOW. No wonder the creators won a Golden Globe.
The script is brilliant. I'd be curious to know who wrote respectively Allison's and Noah's perspectives, or did the screenwriters write them together?
I'm particularly fascinated by the possibility those same facts can be elaborated and interpreted in a completed different way by a female and a male's mind, and so memories are inevitably played back through a personal-bias filter.
It all starts in an interrogation room - just like in Big Little Lies - where it's implied that one of the main characters has been murdered. From the way the story unravels, you can make a fair guess of who the character is, and I'll write the name in the spoiler tag below.
The mystery element adds a more intriguing spin to the drama, which works perfectly with the split narrative alone, anyway.
Also, the parallel-world theme reminds me of the movie Sliding Doors, whilst the "pressurised" chemistry between Allison and Noah has similarities with the one between Michael Douglas and Glenn Close in Fatal Attraction.
Finally, it's nice to see Joshua Jackson again. He'll always be my Pacey Witter...
