I am at this point now: 1 episode to go. Haven't read any of the spoilers in this thread, so maybe a surprise awaits.
This show for some reason isn't compelling. Like, I watched the first episode when the show debuted, and I'm still not finished. Seems like one of those shows you're supposed to like because it has all the bells and whistles of a mind bending mystery, but it just doesn't deliver. The main cast is not very interesting, a lot of scenery chewing, and it starts feeling more episodic than it should because they shift time periods too often in the same episode. Maybe a few too many "character building" scenes, I don't know. "Dark" was way better. Not a big fan of Stephen Graham.
