As I realized reading comments online, it was basically a play. Five acts, all happening in a single location (well, two room to be precise), and with the events of the acts following the classic narrative structure.
I love how Sam Esmail manages to do all these kind of things (single take episode, silent episode, play episode) with all these "special" episodes being compelling and propelling the story, without them ever feeling gimmicky or a waste of time.
Also, good riddance for Vera. Fantastic actor, character greatly written, but I always hated those kind of scumbags. I seriously can't stand those violent bullies who are all yo yo ma bitch u gonna respect me bro what did u say I'm gonna kick ur ass. He got what he deserved. Again, congratulations to the actor who, as the rest of the cast, was phenomenal, but I seriously hate and despise Vera and all people like him.
