The only thing I didn't like the ending was that it was very sad. As Mr. Carny will testify, I hate sad endings in books, films, anything. Seeing Mog's body go limp as the power drained from him and seeing Noel cry out was, for me, pretty heart rendering as I connected with both of them quite a bit. Noel's characterisation in LR magnifies the inherent sadness surrounding him.
