These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Complete Monster: Duane Mellor from "Eater" managed to establish himself as more monstrous than a Wendigo of the same show. A Cajun Serial Killer and Eater, Mellor was arrested for torturing, murdering and eating vast amounts of innocent people, often keeping them alive for days so he could cut pieces off and eat them. Once captured, Mellor waits until the graveyard shift before using a voodoo ritual, devouring the souls of several officers with their hearts to take their forms and play a sadistic game of cat and mouse with the young female rookie cop on duty, solely because "I particularly like it when my prey is frightened." When his patience is exhausted, he simply goes for the kill. The only thing close to a standard Mellor showed was his disdain for being called a serial killer: He was An ''Eater'', big difference.
Faux Symbolism: As it's primarily set in a church, "In Sickness And In Health" naturally has a lot of this.
Idiot Plot: "Chance". Everything the characters do is stupid.
The plot is set into motion when the titular Chance (later revealed to be not just stupid but also insane) falls for an obvious Ponzi scheme that requires him to invest $20000 in a Chinese vase under the promise that he can sell it for $45000.
When an antique dealer offers him only $5000, he leaves without taking the vase or the money.
The smoke sets off a fire alarm. Chance destroys it. A security guard calls the store and Chance answers the phone. He fails to deliver the security password required and the guard goes to the shop.
Despite being already night, the light out, the shop closed and the owner nowhere to be seen, the guard sort of buys that this guy that doesn't know where the switches are or what the password is is a new employee in his first day in the shop, and doesn't react until he discovers the dealer's body.
Chance kills him and also stays to clean the mess. The phone rings again and he answers it again. It's the dealer's wife that is waiting for him because they were supposed to start a minivacation that night and he's getting late. He pretends to be the dealer and she comes to the shop.
Not finding her husband, the woman... uh... takes a shower? In the shop? Oh, and Chance kills her too.
And so Chance goes back home with no money and since he has already killed three people, well, he kills his wife too while he is at it, and waits for the police to apprehend him. The end.
Nightmare Fuel: The last scene of "In Sickness and in Health" is perhaps the creepiest part of the episode, especially since Maggie Lawson did such a good job.
What an Idiot: The writer in "The Circle" tells the girls to make light by setting the furniture on fire.
Big Lipped Alligator Moment: Spider-Man randomly leaves to check on Aunt May. This is likely to set up some time for tie-in issues to take place, but it adds almost nothing to the story and various characters call out Cap for sending him off. It's not like we see Dr. Strange check up on Wong.
Like You Would Really Do It: While most people were pretty sure Thor was/would be dead (the previews for future comics even showed his replacement), he's too big to stay out of the picture for long. And indeed, a few months later Thor was back with the living again.
Replacement Scrappy: The guy supposed to replace Thor after this event was already hated by the time he appeared, because he looks like a Nineties Anti-Hero, his appearance and Thor's death mean that there won't be interaction between Thor and Kid!Loki for awhile, he's not using Mjolnir at all, but a weird staff with a heavy head (indicating to fans that he's not worthy to be Thor anyways, since a worthy person can lift the hammer), and for not being one of the many established people who could take over for Thor, namely Beta-Ray Bill and Thunderstrike. Oh, and the fact that in the books out at that very moment, the guy he was supposed to be replacing wasn't even dead yet.
Tearjerker: Tony, furious with Odin, yells that if they're gods, then he'll sacrifice the only thing he can give that's worth anything... and takes a big swig of alcohol... And after so long being clean, too.
