The Staircase - 2022 - 7/10

Michael and Kathleen, power couple, before she is found dead on the staircase.
Did she fall? Was she attacked? Was she murdered?
The first to find her, and suspect number one, is husband Michael.
Challenging mystery series shuffles chronology as much as the theories.
Mixing dead earnest point-of-view testimonies with deceptions and outright lies.
Few perfect couples are ever as ideal as they appear and this pair is a sticky pile.
Unbelievable cast include Colin Firth, Toni Collette, Juliette Binoche, Parker Posey …
Based on true events from North Carolina, though I would advise NOT researching first.
