This is a story I considered below-average to begin with that has only soured in my eyes over time.  It is so forgettable, it is so boring, and it is so lame.  It strikes me as a bad version of a creepy kids story - Coraline without any of the teeth.  I don't think the puppets look very good, and though it is understandable given his age, George's actor leaves a lot to be desired.  It's the kind of story I almost always skip on rewatches, and the few times I have indulged in Night Terrors, it's only really compounded my disappointment.  Rory and Amy feel entirely pointless.  They're not really in this story and feel wasted here.  I'm really not a fan of this one.
