Brilliant acting, beautiful cinematography, crisp and tight plot. While watching this show, it feels as if nothing gets wasted (in terms of plot). Every small action is important. If you like shows where they show you a small unimportant thing that later turns out to be important, this show is fillied with such scenarios. Grim but also somehow wholesome. It's a show where you'll feel and care for the characters. Every person is important. And the attention to details even in dialog is something that I can't stress enough upon. Take this exchange for example:
Junior: Sir I have a theory, this will work.
Senior: you don't have a theory, you have a hypothesis. You haven't proved it yet, so don't call it a theory.
I mean, the writers and makers have kept so many similar dialogues which other shows won't. They chose to focus on small details without compromising in pace and story. No unnecessary heroism, no melodram, just pure logic and emotions.
I'm on episode 4 and so I haven't even touched my remote. I'll say it again: ACTING & CINEMATOGRAPHY!!! One of the best Indian OTT shows so far. Just marvelous.
