Mountain of Madness is one of my three favorite Simpson Episodes ever. When this episode was made it was towards the end of when GREAT simpson episodes were being made. Most of season eight was great and season nine was pretty good but following season nine the show did go considerably downhill.
I love the plot of this episode. Whenever Mr. Burns is included as a central character the Episode for the most part is awesome. Especially when Burns is interacting with Homer. So to have an episode where Burns is trapped in a cabin with Homer following an avalanche is great. They just do not make episodes like this anymore.
Highlights of this film include Homer and Burns continuing to talk and creating more avalanches as well as Homer and Burns imagining what each others army would look like.
Overall a great episode, one of the three best and definitely the best episode of season eight.
