I have felt it was a bit slow this season and that it was a bit weird how they had him & Shadow King agree to work together and then David immediately flopped when he was talking to the Monk (which could have been him lying I guess) but then had the Shadow King almost immediately go and provoke the FUCK out of David again. It's sometimes seemed like it was flailing for direction.
But I've also continued to enjoy it and how playful it's been with its structure (It's not structural, but that reveal about his sister - that's the kind of thing that is pretty standard for a comic-fan audience but probably a serious "WhAt?!?" moment for other viewers). I'm still a week behind, but nearly caught up.
