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: Ms. Marvel
Adaptation Displacement: You would be hard pressed to find a person on the street who knows who Ms. Marvel is. It would be harder still to find one who knows anything about Marvel's original Captain Marvel. To this day Ms. Marvel is best known to some people as simply being "that blonde chick Rogue stole her cool 90s powers from."
Base Breaker: Carol's new Jamie McKelvie-designed red/black Captain has been this for some fans. While many people prefer the new costume (intended as a colour-coded reversal of Mar-Vell's costume), some prefer the previous swimsuit-and-domino-mask.
Different artist interpretations of what she does with her hair in costume all have fans and detractors.
The decision to "promote" Carol from Ms. Marvel to Captain Marvel (for no better reason really than they won the rights to the name from DC and needed to pin it on somebody so they could keep the name) has also been this for some fans - some see it as a natural progression of the character, even going so far as to say that the name should have gone to her a long time ago, while others actually see it as a step back for her, saying that it takes away from her distinction as a character and that it sacrifices her individuality and identity by forcing the moniker of a previous character onto her instead of allowing Carol to simply be herself.
On some forums, her Captain Marvel book is one of the best, if not the best comic book in publication right now, and its a great relief for Carol to finally get the push she deserves. On other forums, the book is a waste, and so many other characters should have gotten the space for an ongoing instead of her.
Crowning Moment of Heartwarming: In the aftermath of the Skrull Invasion, everyone looks at Spider Woman with suspicion. Ms. Marvel was the only one who approached her and gave her a hug of relief.
To the point of eventually taking on the name Captain Marvel herself.
Fan-Preferred Couple: Thanks to Brian Reed, she was potential love interest for Spider-Man. Since their first date, nothing's come of it outside of them becoming close friends and mild flirting from Spidey, though when Carol herself was taken over by Venom, he hints to Spidey that his crush might not be one sided.
Les Yay: With Jessica Drew and Jessica Jones, which is perhaps more impressive for not being Claremont's fault.
Memetic Mutation: Her new Captain Marvel outfit as designed by artist Jamie McKelvie, has gotten this reaction from fans, with plenty of fan art and cosplays of said costume popping up since being introduced in the Summer of 2012. Encouraged by the comic itself; one of Carol's friends makes her a hat based on the outfit's design.
Judging by the positive reaction her latest ongoing series has gotten (or was getting initially), Kelly Sue De Connick is looking like she'll reach this status with the character. Others prefer Brian Reed to Kelly Sue however.
Never Live It Down: The entire "Marcus Kang" incident, combined with Rogue stealing her powers and memories, sidelined Ms. Marvel for years until Kurt Busiek brought her back as a main character in Avengers. It took her own series to undo a lot of the damage.
The Woobie: Carol's had her fair share of Woobie-worthy moments - screwed over by a jerky father, crappy boss, brainwashed and raped repeatedly by a super-villain, lost her powers and was left to drown while in a coma, more problems with powers coming and going over the years, struggled with alcoholism, depression, on again/off again inferiority complex, unfulfilled love life, misguided and ridiculous jokes against her body, may or may not have been forced to float naked in space by the Brood (and was actually experimented upon while naked by the Brood), etc.
