Not a fan of "creepy clown" type episodes, but this was done pretty well. We get an interesting alien that's a personification of fear, that reminded me of a cross between the Toy maker and Voyager's The Thaw episode.

Also, we meet Rani and her family!

Stephen King’s IT is mashed up with the legend of the pied piper to form a derivative but fun 50 minutes. It’s carried by the excellent cast of characters, including the new Rani Chandra and her parents who reassure us that we won’t be missing Maria too much (if at all!) The headteacher / Chandra’s dad subplot is more compelling than the clown being “destroyed by laughter”. A twist on the well worn “power of love” endings that plague fiction (and so much Doctor Who!)
