Shrunk

The final in the Dark Tower series. Being a creature that thrives on fear, if someone is not afraid, it loses power, and these brave kids overcame their fear. I mentioned James and the Giant Peach before, and James overcoming his fear of the rhinoceros. I picture this as like that film's ending: Georgie and Vicky telling Pennywise they are not afraid of him, he loses his power and control and shrinks. So like Chapter Two, but without the bullying aspect, more like facing their fear and finding power in that.
