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: Uncanny X-Men
Alternative Character Interpretation: The intention is to give this. Either, Cyclops and friends are put-upon heroes who're doing the damnest to save the mutants in danger regardless of the way they're treated, or they're an unstable Villain Protagonist team that are using means not justified by the goal. The tagline when advertising the reboot was literally 'Mutant Revolutionists or Dangerous Terrorists', proving that this is intentional.
Fabio, for being basically the underdog who repeatedly, and unexpectedly, proves very useful in the most dire of circumstances. Even armed with the incredibly lame power of shooting gold balls from his body, he still makes good use of it when he has to protect his friends.
Fan Dumb: There are a lot of people who joke about Hijack having a ridiculous powerset. They conveniently oversee the fact that his powers are simply technopathic, which is an ability that has been used in the comics for decades.
Narm: Pretty much any time Bendis wants to remind readers that Eva is Australian when she's startled, he just inserts the word 'crikey' randomly. Except the way he writes it, it doesn't sound natural at all, so it's hard to take seriously and just comes off as awkward.
Pandering to the Base: Uncanny X-Men #3 is basically written as a "Fuck you, Avengers," issue for disgruntled X-fans, complete with Emma telling Tony he is the one responsible for the Phoenix 5 being born.
What The Hell, Costuming Department?: More than one person has expressed disdain for the new looks. Be it Cyclops' X-shaped visor (that makes it questionable on how he sees with it), the fact that both Emma and Illyana are wearing almost nothing, or Magneto's bald head and white drapes, in general the costumes aren't popular.
The Woobie: Everyone. Scott and Emma suffer from the consequences of being Phoenix hosts, as does Magik, who could be dragged into Limbo at any moment, Magneto (like Scott and Emma) has his powers broken and mourns the loss of his friend Charles and all the teenagers have just been ripped away from their normal lives into an underground life as fugitive criminals, just because their genes were altered (and because Cyclops' team got to them first)
