Acceptable Targets: The wealthy. Not only are they generally blamed for most of the problems of Gotham, Kate resents having to help them out.
Arc Fatigue: Alice has been the main villain for most of the first season, and Kate's quest to get through to her and restore Beth has made up about half of that, with relatively little progress. While some viewers adore Alice as the main or sole draw of the show, others are getting sick of Kate fighting the same villain nearly every week and apparently not making any headway.
Author's Saving Throw: One of the more contentious lines from the first trailer ("They think I'm him. I'm not about to let a man take credit for a woman's work.") was cut from the final pilot. If anything, she was happy to let the idea that Batman had returned make her secret identity all the easier to keep.
Captain Obvious Reveal: Anyone with even rudimentary knowledge of the Batwoman comics would know that Alice is Beth Kane. Luckily they put the reveal right in the first episode rather than making us wait weeks on end. The fact that they Never Found the Body was presented about a minute before revealing Alice's identity, as if the writers knew this could not exactly become a season-long mystery.
Complete Monster: Miguel Robles, a corrupt member of the Crows, is also the murderer of Lucius Fox. After he accidentally shoots Fox while roughing him up for his journal, Robles attempts to cover his tracks by framing an innocent man and, years later, sending assassins after those who could expose him. When those plans start to unravel, Robles takes on the mantle of the deceased Detonator, kidnapping people and encasing them in explosive vests with chances to save themselves by pressing a button to set off another bomb elsewhere; these other bombs are placed in buildings that contain information that might incriminate him, and thus Robles doesn't care if he kills dozens or hundreds of innocents to escape his punishment.
Fan-Preferred Couple: Fans tend to ship Kate with Kara Danvers, Julia Pennyworth or Reagan rather than Sophie Moore.
Genius Bonus: Alices lover is named Charles ("Chuck" for short) Dodgson, the real name of Lewis Carroll.
Harsher in Hindsight: A major premise of the show is that Batman has been missing for a few years, with multiple characters outright stating he abandoned them. Kate herself has doubts about being Batwoman several times in the first season, and at one point stops patrolling for a week. After the Season 1 finale aired, news broke that Ruby Rose would not be returning for Season 2.
According to Caroline Dries, the showrunner, the initial team casting for Kate Kane joked during the process that they needed a Ruby Rose-type, but figured the actress herself would never sign on since she was a movie star known for appearing in big-budget franchises.
Mouse disguising himself as Jacob in episode 7 with his Latex Perfection mimicry is this given Dougray Scott's role in Mission: Impossible II and the sort of technology that exists in that universe.
Incest Yay Shipping: There is a good number of fans who ship Kate and Beth due to Ruby Rose and Rachel Skarsten's chemistry and a considerable amount of subext.
Iron Woobie: Jacob Kane is, for the most part, a guy doing his best to be a decent father, husband and lawful protector of Gotham. Meanwhile, one of his biological daughters is a vigilante, the other other is a supervillain who has tried to kill him, his stepdaughter runs an illegal hospital behind his back, and his wife forged evidence to make it seem like Beth was dead and hiding the aforementioned secret hospital from him. This culminates in Alice murdering his wife and framing him for the crime. The fact that the guy has not been hauled off to Arkham in a straight jacket by this point says something about his mental fortitude.
Misblamed: For Gotham ending and Swamp Thing being canceled. The shows don't affect each other because Gotham is from Fox (and was announced to have been ending way before Batwoman's announcement),Swamp Thing is from the DC Universe streaming service, and Batwoman is from The CW. The latter is especially egregious since Swamp Thing isn't even part of the Batman mythos.
Moral Event Horizon: Alice murdering Catherine cruelly in front of her own daughter and incriminating Jacob is the final straw for him and Kate, who give up on any possible redemption for Alice after this.
At the end of the third episode, Sophie is in her car listening to Vesper questioning what name they should give to the new superheroine. While Vesper mentions many options, Sophie says "Batwoman". The scene should be impactful, but the character cites the name in such a sudden and matter-of-fact way that it comes off as rather odd.
One from the marketing: many fans were quite amused at the announcement for Javicia Lesley being cast as the new Batwoman making such a big deal about her being the first black actress to play the role, as if there was some huge history being upended rather than there only being one previous live action actress who'd ever played the part.
And then there's the fact that Batman: Mystery of the Batwoman a good 17 years earlier also had an African-American character (voiced by an African-American actress) wearing the Batwoman mask.
Narm Charm: Rachel Skarsten's performance as Alice is so exaggerated that it had every opportunity to be disastrous. Instead, she makes the villain fun and at the same time portrays her mental instability very well.
Nightmare Fuel: "Grinning From Ear to Ear" runs on a lot of Facial Horror in general, but at the end there is a lovely shot of Duela Dent with her entire face removed, exposed muscle and all.
Ruby Roses previous acting roles have received criticism for being flat, samey, or even unlikable, but her performance as Kate shows far more range. Shes able to be the usual no-nonsense Action Girl as Batwoman, but is also quite personable with her love interests, has some scenes where she borders on tears (whether from sadness or anger), actually cries a time or two, and even manages some hilarious examples of physical comedy and Facial Dialogue, including through her cowl.
Special Effect Failure: The explosions in Episode 4 have been described as looking like they're from a PS2 game.
Squick: Anything having to do with Mouse's false faces.
Strawman Has a Point: In episode six, Jacob says that Batwoman as a masked vigilante is unaccountable to anyone but herself unlike any licensed crimefighter. While the episode plays Jacob's hatred of those who were the Bat symbol as Irrational Hatred for Batman not saving his wife and daughter, he isn't wrong about Batwoman being a vigilante who is unaccountable to the law and one whose identity isn't public at that.
The first official trailer for the series was completely flamed on YouTube, with more than four times as many dislikes than likes and many negative comments.
A lot of negativity was heaped on the "Times Are Changing" TV spot, which has ten times as many dislikes than likes, along with similarly critical comments.
There was also a lot of bile spewed at the "Night Ride" spot even though it was just Kate getting on her motorcycle with stylized imagery, with no lines or acting to specifically criticize.note The much-maligned "I'm a woman" song played during it, but with no lyrics.
The announcement at ComicCon stating that Batman will not initially make an appearance soured a lot of fans, even though part of the whole premise is that he's gone missing.
The good version of Beth Kane who came from another Earth. Some fans think that even if the writers' intention from the beginning was for her story to end in tragedy, they could have made it last well beyond just three episodes. In particular, it is disappointing that Jacob never had a chance to meet this version of Beth and participate in the same conflict as Kate over which of the two versions of Beth they should save.
The fact that the first season revolved around a villain obsessed with Alice in Wonderland and didn't include Batman's most infamous Wonderland inspired villain The Mad Hatter.
Unintentionally Unsympathetic: Kate can be unintentionally unsympathetic at times, especially with regards to her repeatedly letting Alice go, resulting in the deaths of many people (including her step-mother Catherine), and the attempted murder of her father Jacob, whom Alice also later framed for Catherine's murder. What happened to Beth is unfortunate, but Alice repeatedly tried to drive home that Beth is gone and isn't coming back.
WTH, Casting Agency?: A minor example; no one ever expected Rachel Maddow to act (even if merely as a radio host) in a superhero TV show, but it's mostly because she's a news personality/talking head first and foremost.
Rachel Skarsten's casting as Alice was well-received by many, including some who were not on board with the series beforehand.
The wig remained a controversial choice for a while, but a lot more people got on board when the first trailer revealed Kate started using it due to her annoyance at being mistaken for simply being a returning Batman after her first night on the job, making sure Gotham knows a different vigilante, and a woman to boot, is their protector now.
The confirmation that Kate would remain visibly Jewish in the series was generally approved of, though marred somewhat by the simultaneous reveal that a bat mitzvah scene was apparently cut from the pilot for time (a similar scene was shown later in the first season).
