Definitely the most effective TARDISode so far.

Showing us how the granny lost her face while hiding what actually happened to her and not showing The Wire either. The filter used for seeing through The Wire's PoV is also really fun, especially how it disappears when it comes out of the TV to attack.

Then that final shot of the TV talking about the coronation, with what's just come before, is pretty ominous.

I am shocked myself for rating this so high, because I do NOT like Idiot's Lanterns, that said this one does all what it sets out to do well. Sure, some of it looks fairly dated due to the poor Quality Version that I was watching of it, but it's effective and isn't undercut by a dumb Stock Sound. It even adds something to the Episode, I am surprised how the worst Episode of this Series seemingly got the best out of those Minisodes!
