- Bizarro Episode: Even by Treehouse of Horror standards, "The Diving Bell and the Butterball" feels very out of place (and more like a condensed failed plotline of the show proper). The ending with the sudden transformation into a Spider-Man parody only makes it worse.
- Captain Obvious Reveal: Considering we've heard God's canon voice several times throughout the series, the reveal of Homer imitating God was the farthest thing from a surprise. Homer's well-established hatred of Flanders, Ned's targets being those who have angered Homer in the past, and the fake God voice sounding very unconvincing certainly didn't help.
- Fridge Brilliance: It's somewhat Hilarious in Hindsight that Maude would be revealed as Satan's lover, considering Ned himself took on the role of The Devil in Treehouse of Horror IV and Treehouse of Horror XVIII.
- Funny Moments: There's something poetically amusing about seeing God strangle Homer with two of His fingers.
- Nightmare Fuel:
- Homer tries to make off with the kids' Halloween candy in the introduction, but falls and gets caught in the rocks. He (rather graphically) chews off his arm, only to discover his bag's been switched with a bag of veggies.
- Despite the issue mentioned under Captain Obvious Reveal, it's still rather creepy how easily Homer was able to sway Ned into murder, simply by playing on his Christian devotion.
- Squick: Kamala as a whole is extremely (and deliberately) gross.
- We're Still Relevant, Dammit!: The episode is frequently criticized for its Avatar parody, coming a little too late to have as much effect as they'd like.
