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.
YMMV: The Mighty Thor
Broken Base: Thor's fans disagree over his treatment by Marvel.
No longer the case with Thori now that he reveals his allegiance to his father, Hel-Wolf.
Volstagg was an Ensemble Darkhorse long before them, especially when we got to see how awesome of a father he was.
Thunderball, as the lone smart guy, tends to get plenty of solo appearances and more prominent usage than the rest of the Crew.
Hilarious in Hindsight: Loki got reincarnated as a boy, and Asgard wants him dead? Not only that, but he's also solving the mysteries that surround him with his female sidekick? And adding to that, he solves a mystery which involved extracting evil nightmares from suffering dreamers? Sounds sort of familiar...
Jerkass Woobie: No matter how you feel about Kid Loki, his methods, or if Ikol has a bigger plan in store for him, watching him in the new Mighty Thor issues eight and nine, first struggling to remember his brother and then after achieving that having to deal with the fact that no one else does just makes you want to hug him. He also only really acted like a jerk to Donald Blake after the doctor asked how Loki could forget Tanarus, driving the knife deeper.
Idiot Plot: Any plot that involves Thor or anyone else trusting Loki becomes one of these after, oh, his tenth betrayal (so, since the mid-1960s). The current mega-arc by J. Michael Straczynski would be the most recent example.
Of course in JMS' story Thor and most of the named Asgardians didn't trust Loki (except for Balder) but Loki used Thor's words about Asgardians getting a fresh start on Earth against him.
It's like that in the original myths, too. Loki's REALLY good at getting people to listen to him who should know better by now.
That's debatable. The gods in the original myths didn't trust Loki as much as they tolerated him as long as he made up for the trouble he caused.
Magnificent Bastard: Loki. He's frequently viewed as nearly harmless because most of his plots are just staged entertainment to occupy his near immortal life, but this undercuts just how dangerous he is when he gets serious. Loki is the god of mischief and obfuscation, and other big powers like Dr. Doom and Mephisto tread on eggshells when he comes knocking.
And the distinctly more confrontational: "Your god was nailed to a cross. My god has a hammer. Any questions?"
Moral Event Horizon: In his most recent issue, the first thing Malekith the Accused does after escaping Niffleheim is to massacre an entire dark elf village in Svartalfheim, his home world. He stays past the line when he decides to kill many other dark elves that have scattered throughout the nine realms with his own loyal army, believing that they are no longer the people he used to rule.
This is the only reason Frog!Thor works. The whole storyline seems ridiculous, but the frogs are just so... noble. And once you're sucked in, you can ignore how absolutely bizarre the actual Frog!Thor looks.
Older Than They Think: The idea that Thor is blond and clean-shaven is not Marvel's. There's a painting◊ done by a Swedish artist in 1872 that features a similar Thor.
Uncanny Valley: Loki's female form (as drawn by Olivier Coipel) is unsettling and creepy despite him inhabiting a beautiful body. The reason? No eyebrows.◊
The Woobie: Kid Loki is slowly turning into this. Thor's dead, but Kid Loki can't remember him and then he can but is still the only one who knows Tanarus isn't him. And everyone in Asgard hates him again (to where other children punched him for considering talking to Volstagg when the man was dressed as Santa). The All-Mother want to protect him and consider him a good asset, but he must remain a secret asset and so the abuse continues. And he's living in a hole in the ground. And tormented by nightmares of Thor that he can barely remember when he's awake.
He seems to be dealing with it as best he can, though, sliding more into an Iron Woobie.
And by the end of the Manchester Gods arc he's screaming and sobbing. They're going for full-out Break the Cutie with him.
And in Journey into Mystery #645, oh boy, does Marvel break him.
