Ass Pull: Sam Bradley, Jr. gets revealed as baby Helena's father in the post-One Year Later comics after numerous hints and teases (most obviously the name) that her father was Bruce Wayne. Not only did Selina and Sam barely have a relationship (the night of Helena's conception essentially involves Selina acknowledging Sam finds her attractive and Coitus Ensues) but dedicated fans who did the math on how old Helena was supposed to be, as well as when she supposedly was conceived, noted it made no sense for him to be the father.
Probably the biggest split in her fandom is between fans of her 90's ongoing and fans of the one from 2000's. There are of course fans of both, but you'll rarely hear from them.
Frank Miller's Batman: Year One Catwoman origin subplot that gives her a past as a professional Dominatrix. Quite a lot of people consider it sexist and blatant Author Appeal that is best ignored, but some argue it is a good addition to her history (if more for what later writers did with it than the original story), that makes her a rare example of a positive, non-stereotypical portrayal of sex workers in fiction.
Catwoman being bisexual in the New 52. Some people believe it was handled well and enjoy Selina's relationship with Eiko, others feel DC should have done this with other characters, with larger Homoerotic Subtext and LGBT Fanbase, or not have done it with a character with a previous history of frequent Girl-on-Girl Is Hot innuendo used solely for male-audience fanservice.
Dork Age: Her New 52 book prior to Genevieve Valentine's run is wildly considered to be one.
Ensemble Dark Horse: Catwoman is the most popular love interest of Batman due to her classy cat thief nature and her noble traits.
Fanon Discontinuity: The majority of fans tend to ignore the revelation that the father of Selina's post-Crisis daughter Helena was Sam Bradley, Jr. and not Bruce Wayne, with many considering the reveal an Ass Pull at best. And that's including those who like to acknowledge the existence of that storyline at all.
Hilarious in Hindsight: The rooftop sex scene in the first issue of The New 52 run drew a lot of criticism over the excessive sexualization of female comic book characters. In the Rooftops arc of Batman (Rebirth), Batman and Catwoman have sex, again, on a rooftop, only this time it's done in a more romantic and intimate tone, which ended up drawing a lot of critical praise.
Internet Backdraft: "I am Suicide" had the premise that, among other things, Selina Kyle had killed over 200 people and was scheduled to be executed, with Batman being the one who brought her in for the murders. Her fans, and fans of the Bat/Cat ship, were not amused, with insults and threats being hurled at writer Tom King, and fans were just puzzled on what would lead Selina to kill so many people, even after it was revealed that the people were terrorists who blew up her old orphanage. Funnily enough, while he didn't condone the behaviour, he did encourage the Fanon Discontinuity and Fridge Logic taking place, as this was the mindset that Batman himself had, and in fact, it's revealed she didn't kill anyone; she was covering for Holly Robinson.
Newer Than They Think: Despite being her iconic outfit, she's only worn a black catsuit in the comics since her redesign by Darwyn Cooke in the early 2000s. Prior to that in the post-Crisis era, she usually wore a purple catsuit, and her Golden Age and Bronze Age versions often wore dresses, or leotards over tights. However, her Batman TV incarnations all did wear black leather catsuits, and that probably created the image.
Alternate Character Interpretation: Tom, the detective, is established as being completely oblivious to the fact that his girlfriend and Catwoman are the same person. But, it's actually very possible that he knew they were the same person all along before The Reveal. This is mostly evident by his serious investigation to find out if Patience and Catwoman are the same person and subsequent disappointment after learning the truth.
Ass Pull: Patience gains her powers as Catwoman after she dies and has life breathed into her by an Egyptian cat. Thus gaining the abilities of a cat. Although this was meant to be a Shout-Out to Batman Returns, it was considered to be even more unbelievable in the main story.
Audience-Alienating Premise: A film about Batman's longtime nemesis Catwoman with no Batman in it was bound to be this. Not helping was the film's higher priority on cat-related puns, Halle Berry's sex appeal, and a scheme involving a very dangerous facial cream.
The basketball scene has "Scandalous" by Mis Teeq played over it. It's widely considered to be the group's best song.
The main theme for the movie, "Who's in Control" by Natasha Schneider is a song that's considered to be better than the film itself by some.
Base-Breaking Character: Catwoman is this in her own movie. Either you'll think she's a surprisingly great, entertaining original character or an insultingly cartoony replacement for an incredible comic book character.
Catwoman is a movie about Halle Berry's beauty, sex appeal, figure, eyes, lips and costume design. It gets those right. Everything else is secondary, except for the plot, which is tertiary.
Complete Monster: Laurel Hedare is the scheming wife of Hedare Enterprises' CEO, George Hedare, who proves herself to be leagues worse than her husband. To obtain more money, she produces a skin care product called Beau-line, which has some side effects that make a woman's skin look like living marble if it is used constantly and can also cause a woman's face to get disfigured if the usage is discontinued. After one of her employees, Patience Phillips, accidentally overhears her plan, Laurel then orders her top henchmen to murder Patience in order to prevent the information from leaking out. After Patience becomes an Anti-Hero known as the Catwoman and tries to find the truth about her death, Laurel then tricks her under the pretense that her husband wants her dead. After Patience finds out the truth, she kills both her husband and a scientist, Dr. Ivan Slavicky, in order to frame Catwoman, and tries to ship the Beau-line products across the world.
Evil Is Sexy: Naturally Catwoman falls under this trope, but Sharon Stone's villainous Laurel comes to a close second.
Fetish Retardant: Pretty much everything about Patience's look is considered to be a prime example of trying too hard to be sexy, and failing horribly.
Fridge Brilliance: Many people pointed out that Patience's boyfriend Tom was an incompetent cop who made a simple investigation needlessly overcomplicated. However, since Tom went to great lengths to see if Patience and Catwoman were the same person it's very possible he took his time solving the case because he didn't want to learn the truth. He was afraid of the possibility that the love of his life was a notorious criminal so he went to extreme lengths to see if it was true because he feared destroying his relationship with her.
Halle Berry playing a woman who is ignored by everyone and looked down upon by others can be seen as harsh since after this film was released Berry's career took a serious hit.
Catwoman not gaining a happy romantic relationship with Tom is a lot less entertaining when Batman: Arkham Knight has Batman and Catwoman's relationship sinking at the end of the game as well, with the heroine more heartbroken than in the film.
Idiot Plot: The infamous "handwriting comparison◊" subplot. The film seems to allude to the notion that Patience/Catwoman was the one to write 'Sorry' on two different coffee cups for Tom, while also trying to use different handwriting in order to hide her identity as Catwoman from him. But in reality, it's the barista that usually write names or words on the coffee cup themselves, not the buyer. This makes the 'handwriting analyst' subplot all the more infuriating since the authorities can just go to the store and simply ask if Patience/Catwoman has visited the store before.
The film tries so hard to make an example against sexism (a heroine starring without her usual male counterparts from the comics, a leitmotif about female independence and a mentor who preaches against male academia) that the fact its villains are a cosmetics corporation that plans to sell toxic skin cream becomes unintentionally hilarious, if not downright offensive. It makes it look like, after so much effort, the writers still didn't believe a female audience would get into a plot unrelated to stereotypically feminine interests.
The Problem with Licensed Games: Yes, there was a video game made to tie in with this movie. X-Play said it was like Prince of Persia, "if Prince of Persiasucked." Gametrailers.com had a review saying that it was so bad that it would make you want to drown kittens. Gaming magazines in general were already dreading it in previews and poking fun at EA's attempts to hype the game. Yes, their very press releases were Snark Bait.
Signature Scene: The basketball scene. Tons of jump cuts and wide angle shots, suggestive actions being performed in front of children, and characters who don't seem to know how basketball is played.
Snark Bait: One has to watch the film to get why people poke fun at it.
So Bad, It's Good: Some people would argue that the movie is this. Others argue that it's just bad.
Every single scene with the CGI Patience is terrible. And they did a lot of CGI. It was so bad that they caked makeup on Halle Berry's skin in an attempt to make it look as textureless as the CGI version.
It gets no better with the cityscape or with many of the cats featured onscreen, both of whom are also frequently seen in CGI.
When Catwoman lets Laurel fall to her death, Sharon Stone is very clearly replaced by a dummy as she tumbles down.
When Patience stumbles upon the exposition of the dangers of the make-up, the executive talking about it is supposed to come off as sympathetic. He states that he was fine with all of the cream's side effects (dizziness, fainting, and mental effects) but drew the line at the permanent facial damage that the cream did with prolonged use. It's an attempt at Even Evil Has Standards but many criticized him for willing to turn a blind eye to all of the other, still very severe side effects.
Unnecessary Makeover: The movie decided that Halle Berry of all people needed a makeover, doing this trope twice over.
As Patience, she dons even more make-up, cutting her hair drastically short and donning a tight black leather outfit. The make-up puts her in the Uncanny Valley, the haircut screams "early 2000s" and the main outfit she takes is Fetish Retardant. Patience looks far cuter before the ridiculously sexualised makeover.
As Catwoman, her Beta Outfit is considered to be far more appropriate (in more ways than one) for the character; admittedly it's just a black leather outfit and Domino Mask (she lacks any cat ears), yet many find it far more attractive and evocative of the character than the stripperiffic garb she immediately ditches it for.
WTH, Costuming Department?: Halle Berry's rather stripper-esque leather ensemble and enlarged cat ears have been singled out as such by many viewers and critics. The hat in particular was often compared to a Mickey Mouse cap.
