Really enjoyed Serpent, I swear I felt some panic attacks in some scenes, it’s really gripping.

im not sure tbh, i dont really watch UK TV channels (apart from football)

but seems Hulu has it: https://www.hulu.com/series/mr-inbetween-0c198187-f948-4ccd-b2b4-f5930ca4ac2f

may of been suggested before but Mr Inbetween is amazing, 100% worth a go
