And the line "I'm intelligent and unloved so I see everything!!" also made me go "what?" Did someone not hug you enough as a child, Moffat?

Honestly, I was disappointed in the episode. It wasn't scary in the slightest and this is coming from someone who has had a lifelong fear of the dark. I thought the library wasn't scary and a poor use of the setting. I think it should have been in a museum or something because formaldehyde-filled corpses + dim lighting can be very creepy.
