The Nightmare After Krustmas was a kinda bad episode. However, it isn't as bad as people say. Really the only thing this episode is missing is humor in the A-plot. Come on, the B-plot is soo funny. A parody of the Elf on the Shelf, it's soo clever. Really just for the B-plot I would give like an 7.8. But unfortunately the B-plot isn't the A-plot. Sophie just came out of nowhere from the series. Well, except the Season 12 premiere, but besides that she really came from nowhere. I mean, after Insane Clown Poppy we really haven't see Sophie at all in that long stretch of time. And at the beginning of the episode we see Krusty skating with Sophie? Just weird. Well, let's consider this. Insane Clown Poppy and The Nightmare After Krustmas ( and When Lisa Met Nelson ) are Simpsons episode that exist in there own tiny Simpsons universe. So I'm saying that those episodes are non canon, like That 90's Show, A Serious Flanders, and The Principal and the Pauper. In all, I give this episode a 5.8 out of 10.
