Asylum of the Daleks - fantastic great episode, and couldn’t sleep afterwards. But I can’t help thinking Moffat’s written a great mainstream-friendly episode that would have been better placed in the 2013 50th anniversary season instead.

( Spoilers ahead! )

I can't remember who pointed me to this series of comics on understanding mental health by tallguywrites - possibly actionreplay - but either way, they make for a fascinating and interesting way of understanding a little-understood subject.

And for bonus points, there are also lots of drawing puns based around Daleks.
