This is one of the few series I have actually gone back and re-watched. It's absolutely remarkable. The acting is sublime. Bertie Carvel has a scene where I had to rewind to watch again, it's just that good. This is one of those shows where I recommend to all of my friends. I wish it had more seasons, but it's so perfect maybe it's better being a standalone miniseries. At six episodes it's definitely worth your time.
