I'm usually the first one to state how The Simpsons suck nowadays. I've just rewatched this episode... and I still laughed. This is bizarre. This is legitimately a good episode. I'm scared.
However, I just wished that this didn't have the whole climax of the Nedna business. I didn't care about Nedna. I will never fucking give any sort of shit about Nedna. But it is referenced four times. At the beginning, the cop-out joke, the massive wink and the shit joke at the end. Imagine if the conclusion of Who Shot Mr. Burns took place during "Team Homer". Ridiculous.
So, 4/5. Would have been 5/5 if it wasn't for the constant Nedna referencing.
