Moffat needs to take a break. I think he's stretched to thin to be honest. He wrote some of my all time fave episodes (The Girl in The Fireplace & Blink) & I enjoyed his first season as showrunner.
Also somewhat to his credit is the fact that Matt Smith is probably my fave doctor now (sorry Tom but hey your appearance in The Day of The Doctor stole that episode).
Last season I started vocally expressing my dislike. This season I have just stopped watching. I tried to watch the first episode 3 separate times & fell asleep during each watch. I left the room for the second episode to, wait for it, do the dishes. The third episode having a Robin Hood theme meant I didn't even check it out. I read a glowing review for the fourth (putting it on par with Blink) but I think I need some space before I attempt it.
I also couldn't get past the first episode of the latest season of Sherlock.
