Well that was quite the weird one. A very well designed episode. The Red Lady was essentially just a Weeping Angel and a Siren put together, but was pretty scary.

I almost stopped in the middle, (not a fan of most unexplained creepy episodes), but I finished it. Time will tell how important it is, may skip it next time.

Will skip the next two for varying reasons, curious to see what's next in set 2.
