Finished The Serpent a couple of nights back. Thought it was a slow starter but excellent from Ep2 onwards.
Also finished Designated Survivor a couple of weeks ago - wow, some of the stuff was a bit close to the bone saying it was recorded 2 or 3 years ago! Starts with bombing of the Capitol FFS! Some of the other storylines get a bit close too, but I'll not give anything away for those who haven't seen it.
Just started Mindhunters (Netflix). Set in 1970s, FBI - Enjoying it so far.
