I won’t share anything more to avoid spoilers but I am definitely going to watch part 2.
I did feel there was a little drag in ep four but it kicks back in through the end. There are so many breadcrumbs dropped I have to see the conclusion
My theory, no spoilers, is that episodes 1-6 is only part 1 of a 12 episode season 1. British tv likes to split seasons in half so thinking part 2 could come by fall. Lmk what you think when you finish!
