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.

Many of the New 52 costume changes, Superman's in particular, have come under a lot of fire from fans. Likely to curb these complaints, Wonder Woman's costume had the Painted-On Pants shown during the reboot's promotion removed. However, many fans actually prefer and defend the costume with the pants, partly due to reasons like Diana being too dignified to wear a one-piece swimsuit around and the pointed subduing of out-of-place American flag elements (remember that the character is Greek and is introduced to the United States late in life). It helps that the pants look much better drawn by Cliff Chiang◊, while the fuss-raising promotional artwork was by Jim Lee◊.
Wonder Woman's haughty and short-tempered characterization in the New 52 outside of her own book has also drawn many complaints.
Also in the New 52, the recasting of the Amazons as a people that propagate by seducing and then murdering sailors and then selling their male children as slaves (albeit ones apparently well-treated by Hephaestus) has provoked a great deal of controversy. Some say that this is accurate to Greek myths, while others see it as perhaps the most blatant Straw Feminization in DC history, and question how such a morally corrupted society could produce a hero like Wonder Woman, and how she could grow up knowing nothing about it.
In some cases, it's because fans seriously think Wonder Woman is supposed to date Batman based on the DCAU.
Wonder Woman being the biological daughter of Zeus in the New 52 has also been quite the hot button topic among fans. Some see it as an interesting twist and updating of the character while others see it as a violation of everything Wonder Woman was ever meant to represent.
Common Knowledge: It's widely "known" that Wonder Woman wore a skirt in the Golden Age. And it's true... sort of. In her very first story (All-Star Comics #8), she wears what appears to be a skirt, but isn't. It's actually a pair of culottes — a style popular among athletic young women at the time that resembles a skirt, but is actually shorts. And even those shorts evolved quickly into tight shorts that lost the "skirt" look entirely. Nevertheless, whenever a modern artist wants to evoke a "Golden Age Wonder Woman" look, she's almost invariably drawn wearing a skirt.
DoctorPoison II has only had a few appearances, but has made up for that with the sheer ugliness of the crimes she commits. The granddaughter of a Japanese war criminal, she has continued her grandmother's research, creating new toxins and diseases with which to infect the world. Kidnapping a man named Richard Agoras, Doctor Poison subjected him to lengthy torture and experimentation, ultimately using the Pandora Virus to mutate him into a hideous monster, and unleashing him on Wonder Woman. When captured following this incident, Doctor Poison unleashed the Pandora Virus into the atmosphere, endangering millions of lives. Escaping custody, Poison joined Queen Clea's new Villainy Incorporated, and helped to overrun the nation of Skartaris, requesting that any prisoners they took be turned over to her for further use in her experiments. Obsessed with producing the perfect toxic agents and little else, and making her appearance as horrible as possible in order to maximise fear in her victims, Doctor Poison is as bad as a Mad Scientist can get.
A huge sticking point for many fans is the complete lack of a live-action Wonder Woman movie. With superhero movies being a staple of current Hollywood productions, fans have several reasons to feel like Wonder Woman is getting over-looked.
One of the primary arguments against a Wonder Woman adaptation is that because she is a princess of a warrior race deeply rooted in ancient mythology, she'd be too confusing for a movie. Then Marvel made Thor, which is about a prince of a warrior race deeply rooted in ancient mythology. Given that audiences are generally much more familiar with Greek mythology than Norse mythology, well...
Adding insult to injury is Marvel making Guardians of the Galaxy, which features Rocket Raccoon appearing in a live-action movie before Wonder Woman. Giving the entire world this gem:
An Episode of Justice League had Wonder Woman meeting Hermes with him saying her formality was unnecessary since she was practically part of the family. Come the New 52 where Diana is now the daughter of Zeus.
Informed Real Life Fame: Her status as being one of DC's "Big Three", the other two being Superman and Batman. The sad fact is is that they're both far more popular than she is, and the details of their series are far more well known. Wonder Woman's mythology and supporting cast have often suffered inconsistencies, with even the writers struggling to figure out what her driving motivation is. As detailed elsewhere, most potential adaptations of her end up never being made, with the live action series being the only one that's really well known. She is undeniably famous—but mainly in the sense that most people know of her, less so in the sense that many people know that much about her.
Ink Stain Adaptation: The Lynda Carter TV series, especially since unlike her famousteammates, Diana hasn't had any really well-known adaptations since. When ABC News reported on The Movie, they claimed it would be an adaptation of the TV show with absolutely no mention that, you know, it's a comic book.
My Real Parents: For the modern generation, Gail Simone and Greg Rucka. For a generation ago, George Perez. Brian Azzarello's current run may take him to this status as well.
Strangled by the Red String: Subverted in the Infinite Crisis storyline "One Year Later". It had Diana suddenly involved in a relationship with Nemesis (Tom Tresser), a new co-worker and long-time minor DC character. Many fans felt this new hookup was rushed at best, especially since Tom was considerably more boorish than in previous appearances. Eventually, in Wonder Woman #32, It's revealed that Diana never had romantic feelings towards Tom at all; she was just exploiting his feelings towards her to get him to father her daughters and replenish the Amazon population.
The pants-and-leather-jacket costume introduced in Odyssey has come under fire for this. Especially since that for a 2010 retool, the style seems awfully Nineties...
Because there have been so many failed live-action adaptations of the show, there are a lot of rejected treatments, film scripts and that infamous 2011 pilot floating around the internet. Despite the fact that fans are scrambling for something to happen (considering there have been 8 live-action Superman adaptations and 5 of Batman, fans are afraid that a live-action WW is quickly entering the Duke Nukem Forever territory of being physically impossible to live up to the hype around it), they just cannot agree on what it should be.
Ear Worm: The TV theme song. Sure, Batman and Superman get full orchestras, but only WW gets a funk bassline and backup singers.
Hollywood Homely: Mocked a bit in "Beauty on Parade". Diana proposes infiltrating a USO beauty pageant to find a saboteur. Steve objects, thinking they would need somebody really gorgeous to pull off an undercover like that. Diana does it behind his back, and the enthusiasm from the pageant organizers reveals that Steve is, well, kind of a moron.
Narm Charm: Reaches its peak in "Skateboard Whiz", when Wonder Woman — you guessed it — chases a fleeing car on a skateboard. It is impossible not to love it.
Les Yay: Inevitable given the source material, but practically everyone seems to assume that Artemis is a lesbian in this version.
Magnificent Bastard: Hades, dear Lord Hades. He initially refused to remove Ares' shackles, claiming that Zeus had asked him not to. What he neglected to mention was that Zeus asked him not to because he foresaw that it would get Ares killed.
Hades to Ares when he appears in the Underworld after his death: A tragedy. A terrible terrible tragedy. How it weighs on my heart to see you like this. When my brother asked me not to remove your bands he said I was only dooming you, that he could not save you from yourself yet again. Perhaps, I should have listened.
Narm: Alexa as a zombie finally decides to fight. Awesome! Oh, no. Wait. Ares simply returns all the Amazon zombies to death ten seconds later.
Squick: Hippolyta and Ares have a child, Thrax. In the comics and the myths, Ares is Hippolyta's father...
