Narcos: Mexico Season 3 - Only watched the first two episodes but it is shaping up to be another terrific season.
Succession Season 2 (am saving up Season 3 for later) - superbly written in my view in the sense that it is replete with acerbic one-liners and witty put-downs, though I do get why this series has its detractors. Reminds me more than a bit of the 1950's movie The Sweet Smell of Success, though that film has greater thematic depth and includes characters that one can more readily identify with, as well as ones that are fascinatingly repellent, like Burt Lancaster's JJ Hunsecker and Tony Curtis's Sidney Falco.
Caliphate - a Swedish series that gets radicalization spot-on in my view and is partly based on the Shamima Begum case and those other girls that attempted to migrate to ISIS territory. Exciting too.
