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.
Electrocutioner, for all his bluster, goes down in one hit. Though this is the point.
Surprisingly, Electrocutioner manages to be an Anti-Climax boss twice! Despite it being a relatively late-game unlock, it's fairly obvious that you're going to get an electricity themed gadget at some point, and since you don't get the Shock Gloves from your first encounter with the Electrocutioner early in the game, you might be led into thinking that you'll get them after a rematch that's a "real" fight. At one point Batman has to track down a meeting of Assassins by way of tuning in to the Electrocutioner, and that seems to be priming you up for a fight with him. It turns out that it's just another trick though, as the Electrocutioner is killed before Batman can even lay a finger on him. You do get the gloves this time though.
Lady Shiva starts off as a reskinned martial artist and flanked by four ninjas; after getting her down to half of her health, she switches to a reskinned ninja flanked by three martial artists. The only difference between Shiva and the standard versions of the classes she fights as, is her immunity to Batman's stun and takedowns.
Somewhat averted in the DLC, where she is not only harder, but requires you to cape stun her to damage her, even if your Shock Gloves are active.
Copperhead can appear challenging due to the vast number of duplicates she spawns but they can be easily beaten with counters, letting the player attack her without much resistance.
Awesome Bosses: The Deathstroke boss fight has been particularly acclaimed, as it forces the player to make sure to memorize his attack patterns rather than just spamming the attack button as well as focus on mastering the counter ability, since just rushing in and pressing it as quickly as possible will lead to a very quick death.
The battle against Firefly is also rather engaging as one has to be quick to dodge his fire attacks and then be quick reeling him in with the grapple to cause any damage or one is forced to repeat the strategy. It helps the battle is stretched through the Gotham bridge making it feel more epic.
Some fans are not particularly happy that it's a prequel (mainly because of more than one Sequel Hook in Arkham City and a ton of foreshadowing), while others are rather intrigued by a game set before Batman became trusted by the police, a la Batman: Year One.
And the fact it has Multiplayer has ticked off a few as well, while some are excited to play an "Arkham" game with friends.
It was confirmed that the Wii U version will cost less as compensation for not featuring multiplayer. While great news to Wii U owners, Arkham players who want to play the game on other platforms and do NOT care about the multiplayer are not pleased that they are being forced to pay for a feature they don't care about (although the console game's price is identical to the previous Batman titles which had no multiplayer, so arguably it is a free bonus).
The Joker being the villain, and that he ordered the assassins to go after Batman by impersonating Black Mask hasn't gone over well, because there was a lot of hype surrounding the fact that someone other than the Joker would function as the primary villain. Some people think it was a wasted opportunity and predictable, but some fans enjoy it because the game explores Joker's psyche more closely than the previous games did, and because he's a popular villain, hijack or not.
Similarly, though the devs never hyped up Anarky as a replacement for the Riddler, many commentators speculated that he was, leading to confusion on the part of gamers who never followed up on sources. Anarky gets a brief sidequest, while the true "replacement" for Riddler is... Enigma; who is the Riddler. Some are irked that another well-used villain takes the place of a lesser-known one hyped to be important, others found Anarky's shtick to be annoying, and are glad to see an origins for the Riddler, rather than having him replaced by a b-lister at best.
A more minor one in the issue of Deathstroke appearing as a high profile antagonist in the game. Some take issue with the fact Slade isn't specific to Batman's rogues gallery, which doesn't gel entirely well with the game's nature as an origin story. Others are excited to see one of their favorite DC villains receive an Arkham debut, and that he's also playable.
There's also some bugged that his role was so minor. He's fought very early in the game, comes out of nowhere and is dealt with after one fight, and save for a cameo in a later level and post credit scene, he bares no impact on the plot. Given how he was hyped up a lot, and was the only assassin who's also playable, it comes as quite a disappointment given he could have at least had his own sidequest, if not his own playable missions like Catwoman did in Arkham City.
The lack of alternative playable characters beyond Deathstroke is another. While playable in the Multiplayer, Robin isn't featured as a playable character like he was in the previous game, nor is Nightwing or Catwoman. As such, some who enjoyed them in the previous game and wanted to play them again feel disappointed, while those who didn't care for them, well, don't care.
Fanon Discontinuity: Despite the fact that both Warner Bros. and Rocksteady have confirmed that Arkham Origins is a legitimate canonical prequel, certain fans absolutely refuse to consider it canon to Arkham Asylum and Arkham City due to its glitches, minor continuity errors and because it was developed by WB Montreal.
On the flip side, some fans welcome Origins' story but refuse to accept its gameplay, for the same reasons as above.
Foe Yay: When The Joker's being psychoanalyzed by Harley while detained in Blackgate, he starts narrating his origin to her: being the Red Hood and the fateful bath in chemicals courtesy of Batman that transforms him into his present state. In his mind, he's imagining a horrifying ordeal; narrating it to her, Harley interprets it as him being in love with a special someone. And the dialogue even suggests that he's fully aware of such a thing, using his words to convey his true feelings about Batman while being vague enough to play on Harley's emotions.
All combat challenges become a breeze after one acquires the Shock Gloves. Once activated, they can punch through any measly defence that the mooks might have, and they double the hits in the combo counter, making it easier to pull off special combo moves.
In addition, some campaigns allow you to use an ability that allows you to punch through shields, armor and batons, like in Arkham City. The difference here is that instead of just doing that, the power-up simply gives you infinite shock glove use during the fight. Combine that with the shock glove's multiplier effect, and it's not that hard to get triple the points needed to get all medals on that challenge.
A big deal was made about how hard the I Am the Night -mode was going to be, since the player has only one life to beat the game with no saves... except the developers forgot the last part, and the player can use the restart feature between checkpoints with no repercussions as long as they don't die.
The remote claw in the predator sections allows you to take out any henchman that so much as wanders near a gargoyle or other vantage point from a distance. Since they're everywhere, they make those sections a lot easier than they really should be.
If you're ever overwhelmed by groups of thugs in the streets, the Enhanced Dive Bomb makes it insanely easy to whittle down forces. Dive Bomb, grapple away, repeat. You can even use the glue mine for ensured multiple knockouts.
Deathstroke and Bane both play major roles in the game, with Bane eventually turning out to know who Batman is, but then loses his memory due to a combination of chemicals. Cue Beware the Batman, where Deathstroke appears... And his fate and motivation is identical to Bane's.
It's the Same, Now It Sucks: The most prevalent complaint against the game is that it doesn't do much that the previous games hasn't done.
It Was His Sled: Anyone who's read the comics will know that Anarky's a lot younger than he appears to be, though some people may have been expecting him to get an Age Lift.
Or that Ferris Boyle isn't half as nice as he seems.
Jerkass Woobie: Black Mask. By the end of the game, his life is ruined, he's been forced to Mercy Kill his girlfriend, he's been beaten and tortured, his crew is in a bad way due to the Joker, and on top it all off, he's blamed through the game for things he never even did. When he's seen trying to build himself up again, it's kind of sad, since he was a big-time crime boss and is now forced to do a low grade drug smuggling operation just to be noticed again.
Anarky. It's clear that he's a rather angry and embittered young man who simply wants to do what he can to handle the intense injustice and corruption that permeates throughout Gotham city. When you beat him, it's kind of hard not to feel a little bad for him. However it's his extreme terrorist methods that push him into the 'jerkass' territory.
Older Than They Think: The Shock Gloves aren't actually a completely new gadget. They first appeared as an upgrade in the mobile "Arkham City Lockdown" game and "Arkham City - Armored Edition". However, in those games they were only used for combat, while in Origins they're also used to solve puzzles.
Play the Game, Skip the Story: Inverted. The story was widely praised, but the game itself was criticized for severe bugs and a lack of innovation.
Porting Disaster: The Xbox 360 was plagued by freezes, black screens and save-file corruptions when it was first released.
The Scrappy: Tracey Buxton, due to her grating voice and dated British cockney slang that makes her a living caricature.
So Okay, It's Average: General consensus on the game appears to be that it's fun to play and has a strong story, but does little to improve on its predecessors.
Special Effect Failure: In a game that's remarkably detailed and well designed, the flat fire effects in Joker's Blackgate takeover really stand out.
That One Achievement: "I Am The Night" which requires the player to complete the Harder Than Hard "I Am The Night" mode, which challenges the player to complete the game on a single playthrough with no continues.
Three of the eight assassins are defeated fairly early on in the story (with the first being the one who introduced the entire concept in the first place as the Warmup Boss), and two more are only Bonus Bosses.
Early on in the game Calendar Man is freed from prison during the Blackgate break-in. You'd think that since it's Christmas and that he's a Serial Killer whose murders fall on holidays, that Batman would make it a point to track him down. Instead Calendar Man just disappears from the rest of the game and Batman never tries to find him. The only thing that stops this from being a What Happened to the Mouse? moment is that we know from Batman: Arkham City that he's spending the holiday murdering Judge Harkness at the Judge's Christmas Party. But the fact that this game hyped up its Detective Gameplay you would think you would investigate said murder and bring in Calender Man. Sadly no such luck.
Similarly: The game is set on Christmas Eve, Year Two. You have a game-mode where you solve mysterious murders? Alberto Falcone is in the game. Seems like a perfect setup for something relating to The Long Halloween, right? Also with the hype having been focused on the regular criminals, neither the Falcones or the Maronis have a big impact (or barely appearing), while in the comics they were the biggest foes in Batman's early career.
At first, Roger Craig Smith and Troy Baker appeared to be fighting an uphill battle as Batman and The Joker. Doubly so since they're playing a younger Kevin Conroy!Batman and Mark Hamill!Joker. Some of the sting is taken out of it in that they're meant to sound younger, and thus different. And indeed, both voice actors emulate Conroy and Hamill passably, but not perfectly well, enough to sound like the same character at a different age. The alternative is to give a Batman in his 20s Conroy's classic but weathered voice.
Values Resonance: The "Cold, Cold, Heart" DLC is a direct adaptation of the classic note As in, considered to be the Growing the Beard moment for the seriesBatman: The Animated Series episode "Heart of Ice," following the same beats of the story rather closely. It even follows a lot of the most powerful emotional moments of that episode, with many pointing out this just only proves just how timeless the original story was. "Take a seat, humanitarian."
What The Hell, Casting Agency?: German version only. The VA of Joker didn't even try to sound at least a bit different in the lines where Joker impersonated Black Mask, thus the plot was spoiled during the first 10 minutes for everyone who has an average sense of hearing and who can count two and two together.
Plus, the german dub didn't switch voice actors for Batman and Joker like the english-speaking version and stayed with the voices from the previous games, which is rather jarring for the people who care about this.
