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: Beware the Batman
Alternative Character Interpretation: In "Hunted", Pyg and Toad often state the importance of nature, but some people note that it seems almost like a secondary goal that they're using as an excuse to go out and murder some millionaires.
Author's Saving Throw: Harvey Dent's inclusion and his transformation into Two-Face can be seen as this to those who denounced the show for omitting the famous Batman villains and focusing solely on his more obscure foes.
There are those who refuse the show outright simply because it's CGI.
Alfred using gunsnote which, along with the other guns in the show, were replaced with pulse rifles following the Aurora rampage to fight crime alongside Batman and Katana using her, well, katana—making it appear as if Batman is using lethal force—has turned a few fans off.
The inclusion of Katana rather than any of the Robins or Batgirls has also soured many fans, given several of them have yet to appear in any adaptation.
The fact that it's yet another Batman series as opposed to a lesser used hero like The Flash or Wonder Woman hasn't won it many fans.
The show not using classic foes like Penguin, Two-Face, or even The Joker in this series, in favor of altered versions of lesser-known villains.
The show's version of Alfred definitely suffers from Love It or Hate It. Some people like the different interpretation of his character, while others think that he's too different to even be considered Alfred. Others just think he looks weird.
Continuity Lockout: The series seems to be growing into this, as episodes next week almost always continue off of the previous one, context is of course not always properly explained on Previously On segments, as well as the generally more plotted nature of the series.
Magpie's portrayal in this show has become fairly popular, with fans praising her complexity as a character, her ability to outmatch even Batman in combat, her entertaining dialogue, and her... appealingcharacter design.
Magpie was originally somewhat sexually designed in her original '80s design, but to update her appearance, the show's designers drew on fashion runway models and contemporary pop stars, specifically Lady Gaga, for her new appearance. As the only female antagonist identified early on, she's far more sexual than Katana. In fact, she's more sexual than most depictions of Catwoman.
Lady Shiva. She's a stone-cold Badass who instills fear into an entire roomful of ninjas that don't even flinch when ordered to fight Batman or his equally tough protege. She shows no remorse over ruthlessly overthrowing Silver Monkey and sucking out Dr. Ravencroft's soul. She even manages to give a solid ass-kicking to both Batman and Katana, highly skilled fighters who outnumbered her two-to-one. The clincher? She sports a tight, midriff-bearing, Gainax-approved outfit while doing all of this.
Fandom Rivalry: Fans of this aren't happy that Teen Titans Go! has become Adored by the Network and is now pasted all over the schedule, while Beware the Batman is stuck with the same weekend-morning-only schedule as Green Lantern and Young Justice before it. This will probably only increase now that it's been pulled altogether for — what else — more Teen Titans Go! repeats.
Foe Yay: Anarky definitely has a thing for Tatsu, which is really played up in "Nexus".
The show, while not bad, started out similar to other series in that it's got continuity, but mostly standalone stories featuring the characters, and thus didn't really distinguish itself from many of the other Batman shows aside from using obscure or underused villains. After "Safe", the show moved into an arc involving the League of Assassins, which seemed to be plotted fairly well, as well as putting greater emphasis on Bruce and Tatsu's growing as characters.
A character example in this version of Anarky. He started out as a Smug Snake with barely enough skills to back him up and an absurd fixation with Chess. It wasn't until "Sacrifice" that he really came into his own, effortlessly conning Lady Shiva and Batman and taking his loss on the chin and moving on to his next plan instead of getting upset and complaining that Batman doesn't consider him a Worthy Opponent.
When the Joker was killed off in Batman: Arkham City, the fans that weren't ticked off were excited in the hopes that the sequel would show off lesser known Batman villains.
Before the production of this series, the idea of a Superman/Batman animated series was being bandied about. About two episodes in to Beware The Batman, the sequel to Man of Steel was announced to be a Superman/Batman movie.
In Teen Titans when Robin unwillingly becomes Slade's apprentice, he refutes Slade's father son comparison by saying he already has a father, an allusion to Batman. Here in this show, Slade a.k.a. Deathstroke's main motivation is that he is jealous of Batman for being the favored apprentice/surrogate son of Alfred.
Les Yay: In Family, Lady Shiva says that Dr. Ravencroft is beautiful, gives her some affectionate names, and strokes her hair. It escalates further into No Yay when she sucks out her soul in such a polite manner right afterwards.
Love It or Hate It: The show's animation has been hit with this hard. While the show's storytelling and characters have been mostly well-received and the music and voice acting are almost unanimously praised, the CGI animation and overall visual style has drawn both praise and criticism, with some of the latter coming even from fans of the show. Those who like it praise it for its fluid movement, impressive fight scene choreography, unique character designs and dynamic use of lighting. The detractors criticize the CGI as cheap-looking compared to other shows such as Transformers Prime, Star Wars: The Clone Wars, and even the similarly-styled Green Lantern: The Animated Series. They also feel Gotham is too empty, and others still dislike the character designs in general. Another vocal section just hates it because it's CGI.
Harvey Dent was just a Jerkass, but deliberately refusing to quell a prisoner riot in Blackgate on the hopes that they might take out Batman pushed him over the edge.
Magpie crosses this in "Attraction" when after her sanity decimated to a point that she became a psychopathic Stalker with a Crush she attempts to bury Katana alive and then try to kill Batman herself when she gets her heart broken.
Sapphire Stagg crosses this in "Monsters" when it's revealed she is the one organizing the destruction of Old Gotham, endangering lives in the process.
Humpty Dumpty crosses this in "Games" when he devolved into The Sociopath and kidnapped Ernie Croskey to force him to kill the ones who was responsible for his plight that wrongfully sent him to prison. However, when Ernie held no hard feelings against his wrong-doers and just want to return home to his family, Humpty then try to kill them himself.
Narm: Bruce and Tatsu are enjoying time at a diner owned by Wayne Enterprises in "Instinct", but it's mostly to hone Tatsu's skills. When Bruce asks what she sees, and she can't see anything but everyone having a good time but them, and asks what he sees, he says "I see crime.". Punctuated by him explaining the crimes going on, and when he gets to the last one, he says what the crime is before it happens (a pickpocketer stealing someone's wallet), making the scene almost come off as a parody of Batman.
Anarky's reception in his second episode fared quite a bit better than that in his first, due to him actually being portrayed as a competent schemer who is much different in motives and methods than The Joker. His Vocal Dissonance has also been praised.
Professor Pyg and Mister Toad were originally considered pretty poor villains by many people who originally saw the first episode. However, in their second appearance, a lot of people warmed up to them due to their amusing comedic dialogue.
The show as a whole became this for DC's collection of animated shows after it premiered. Prior to the airdate of its first episode, there was a lot of controversy surrounding the series and the overall fan reaction ranged from cautiously optimistic to outright hatred, with little outright positivity. After it finally aired, the show received generally positive reviews from fans and critics alike, who praised the dark tone, the characters (both familiar and obscure), the animation, and the strong focus on Batman as a detective in addition to Batman as a fighter. The appearance of an Adorkable pre-Batgirl Barbara Gordon and her obsession with Batman has quashed complaints about a lack of A-list sidekicks. Whether she becomes Batgirl in this series remains to be seen, but this hasn't stopped fans from becoming excited.
The Scrappy: Harvey Dent, due to his characterization lacking any sympathetic traits, the overall differences between previous incarnations to the point he is near-unrecognizable, and the fact that he is almost entirely designed to be a Strawman character whose arguments against Batman's are meant to be wrong.
Seinfeld Is Unfunny: Word of God says this is at least partly the reason that the they want to focus on lesser used villains like Anarky or Professor Pyg. Since the more famous villains are so well known and often used, they want to try out something new and give Batman challenges that the audience isn't used to him dealing with.
Strawman Has a Point: Harvey Dent isn't going to win any sympathy points with his general demeanor or his questionable methods, but it gets a little hard to fault him for his dislike of Batman and Katana after they sedate him, kidnap him, tie him to a chair and put him directly in Anarky's line of fire, all for a very flimsy reason.
Bruce in "Secrets" when he looks at a Rorschach blot, has a brief PTSD flashback involving him kneeling between his dead parents, and then lies to Dr. Ravencroft that he only sees splashed ink on paper. Batman's quote in Toxic is another flash of this. You illustrate this better than anyone, Bruce...
"There are two things everyone in life is powerless against: Love and revenge." - Batman
Tatsu. Oh Lord, Tatsu. She gave up literally everything she knew, betrayed both organizations she was a member of, faked her own death, and went into hiding simply because it was the right thing to do. Her clear sadness when mentioning her father's death invokes this too.
Alfred. His clear dedication and worry for Bruce as well as his helplessness in the face of him being in constant danger makes you really feel for the guy. The part where his leg is broken is also rather sad.
Magpie in spades. She was formerly a kleptomaniac named Margaret Sorrow. After being sent to prison, she voluntarily underwent a rehabilitation procedure that would cause her to no longer desire to engage in criminal activity. It appeared successful, but only succeeded in splitting her into two halves: a normal, seemingly well-adjusted girl named Cassie, and a violent, obsessive, sociopathic kleptomaniac known as Magpie. Ouch.
Humpty Dumpty. He just wanted to play with his numbers and his toys...
Poor Rex Mason/Metamorpho. Poor, poor Rex. His origin story has always been pretty sad, but the little touches in this version such as him being Driven to Suicideand failing make it even worse.
Man-Bat. Poor guy was just a honest, well-intentioned scientist trying to come up with a serum for medical purposes, only to have his research perverted by Pyg and Toad, who then used it to forcefully turn him into a bat creature. And as if this wasn't enough, they also used a Mind-Control Device to force him to do their dirty work.
