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.
Franchise Original Sin: Robots In Disguise had some issues such as choppy animation, episodes that didn't contribute much to the overall story, too much focusing on selling toys, some annoying human characters, and spotty dubbing and voice-acting. Despite this, it managed to be fairly good and did a lot of things right. It's follow-up, The Unicron Trilogy (particularly Armada and Energon), took everything negative about RID and amplified them by ten while losing track of everything it did right.
Accidental Aesop: You should let go of old grudges. Holding onto them will cause nothing but difficulty, heartache, and pain for everyone involved.
Alas, Poor Scrappy: Metalhawk was considered by many to be annoying with his smug Holier Than Thou attitude, mud-slinging, and hypocrisy (trying to make a better world all the while belittling the aligned forces and straining the alliances). He's betrayed and killed by Starscream, whom he considered a friend, and his death was then used to accomplish his stated goal. Then he came back as a very angry zombie...
Ironically, the characters you'd least miss in this series' first arc (Bumblebee and Metalhawk again) are some of the ones you'll miss most after finishing Dark Cybertron.
Galvatron vaporizing General Witwicky elicited this reaction.
Alternate Character Interpretation: The Monstructor Six. Was Jhiaxus lying when he said they volunteered for the procedure (considering his track record and Arcee, he may have been)? Were they willing accomplices to all of his plans, or are they just Slave Mooks with their free-will stripped in pursuit of the idea that "all are one?" Or is it a combination of that, with their minds destroyed or broken down, and them willingly following Jhiaxus as they can comprehend no other alternative? Bludgeon implies that it's the latter, but he's hardly the most trustworthy person. Galvatron inadvertently chimed in on this later on when discussing combiners he believes that those who combine have their personalities dilute themselves until their individuality rots away. This combined with the long period of time the Six have combined in addition with him being a flawed prototype, can also account for their mindset.
Awesome Art: Livo Ramondelli's drawings aren't universally liked, but when they work, they work.
The three-artist team working on "Earthfall" (Guido Guidi, Brendan Cahill and regular Andrew Griffith) all pick up each others' slack really well. That their art is very Alex Milne-esque helps.
Awesome Ego: Deconstructed. Nova Prime starts out as fully deserving his ego, but eventually this degrades into him thinking he's a gift to the damned universe and causing him to become a self-loving extremist.
Turmoil, surprisingly enough. Some fans think he's a cool original character, citing his design and badass nature. Other fans think he's just a generic "high command" con who exists to look threatening and give brownie points to whoever kills him. Some think he was underused, others just didn't regard him as important. Issue 7 billed him as a fan-favorite character, people either disagreed as he was from Drift's run, were glad to see his return or treated his reintroduction with a "meh."
Given that his time machine is essential to Shockwave's plan in Dark Cybertron, it seems he was heavily promoted to avoid a Continuity Lockout.
Rattrap's Adaptational Villainy started the fractured fan opinion about him. Ruining of an iconic character or interesting new direction?
Alpha Bravo caused a divide even before he appeared in comic. The biggest reason is him being a Canon Foreigner, and replacing Slingshot. His detractors feel he throws off the all-plane Aerialbots by having a helicopter mode, and his whole appearance is a blatant cost saving measure (his mold can easily be redone to create Blades and Vortex). His defenders feel he adds some diversity to the team by breaking the mold, and feel the cost-saving measure is a necessary set back to finally give the fans the well-articulated combiners they've always wanted. Then of course there's the Slingshot fans who feel the character's gotten the short-end of the stick, though this has lessened with the announcement of a Slingshot figure (retooled from Fireflight).
Broken Base: Unlike it's near universally loved sister series More Than Meets The Eye, this series is was the divider amongst fans for quite a bit. It's starting to be much better recieved, though.
Season 1 had it's fans, the continuity was much tighter, the cast had more of the big names in meaty roles, and Post-war Cybertron was ripe with new story ideas. It also had it's detractors, some felt the pacing was very slow, the Autobots and NAILS came off as too unlikable, and Megatron's return while a fun arc made him seem too generic.
The Base hasn't broken yet on Season 2, but there are fears, even pointed out by podcasts, about RID returning to Earth, since it will have to touch on the maligned Costa run, more specifically International Incident. But hey, at least it's not Heart of Darkness.
There are arguments brewing over the EDC teaming up with the Decepticons, which some feel is a nonsensical plot twist given the events of All Hail Megatron. Somewhat lessened by the fact that Soundwave makes sure to distance himself from Megatron, and that current leader Galvatron actually helped defend humanity during Infestation.
Darkness-Induced Audience Apathy: Quickly heading that way. The Autobots, Decepticons, and Nails are all assholes excluding a small few exceptions (Wheeljack, Sky Byte, Dirge, Scoop, and few others). Everytime the heroes seem to be getting anywhere, something comes along and bitch-slaps their victory away. Save New Iacon from Megatron? Starscream kills Metalhawk, screws over everyone, and takes control of the city. Orion and his team reach some of the ores before Jhiaxus and Bludgeon? Jhiaxus and Bludgeon outwit them and get it anyways. Some fans have stopped reading simply because they think all the likable and sympathetic characters are getting killed off and ignored in favor of detestable and annoying Designated Hero characters.
Thankfully season 2 seems to have largely fixed this, with the jerkassery of the less likable Autobots being reeled back (making Bumblebee and Metalhawk much more popular), the focus getting shifted from Bumblebee to Optimus, and a more humorous tone being added, giving the comic a tone more consistent with MTMTE and Windblade.
Designated Hero: Sideswipe is an Autobot, but he acts like a complete lunatic who constantly provokes fights and talks about how much he loves to engage in violence. On multiple occasions he's talked about shooting/beating up Decepticons and NAI Ls for fun and during the annual. No wonder the Nails hate the Autobots when they've got psychos like Sideswipe around. Likely intentional, though to what extent isn't clear.
Ensemble Darkhorse: Dirge is one with both the fans and the creators. Waspinator and Sky Byte were included solely because they were popular.
Pretty much everyone will agree that this iteration of Shockwave is completely, terrifyingly awesome.
Thundercracker was already an Ensemble Darkhorse in the previous ongoing, so his return here was met with much praise, especially given his development into a complete dork who has an adorable puppy and spends time writing awful screenplays for fun.
Amongst the new cast members joining in season 2, Cosmos seems to be getting the most fan love due to his earnest yet snarky personality and woobie-factor. It helps that he's a carry over from MTMTE.
Wheeljack is beloved by fans, many feeling that he should be the main protagonist. Not surprising given his popularity in previous G1 stories.
Fan Nickname: "Prowlestator" for the new form of Devastator with Prowl in Scrapper's place.
Crackerjack for Thundercracker, in light of his horrible fanfics.
"Captain Continuity" for John Barber, who goes to incredible pains to try to patch up every single plothole from all the way the "-ations" series.
Growing the Beard: Some feel that the comic is starting to grow it's beard with issue 16, where Starscream takes over New Iacon (creating an interesting new setting) and starts to feature a more character driven story. Bumblebee also begins to become significantly more likable during this time before being done away with in Dark Cybertron, finally giving the other more interesting cast members (besides Starscream) a chance to take stage.
Harsher in Hindsight: Generation 1 Superion was toy of notoriously poor quality, whose legs tended to snap off at the waist. In addition, the Generation 2 re-release had one of the components, Slingshot, suffer from the toy-destroying Gold Plastic Syndrome. Devastator rips Superion to bits in exactly this fashion in Issue #15, and irreparably and fatally injures Slingshot in the process.
Holy Shit Quotient:The entirety of the "City on Fire" arc, but a special mention goes to Prowlestator.
I Knew It: There were some guesses that the Constructicons didn't die, as when "Prowl" triggers their detonation chips, the explosion comes from their necks and consumes their heads in fire (silhouettes still visible), instead of blowing them to bits like Horri-bull.
Iron Woobie: Wheeljack is under-appreciated, often berated except when his science skills are useful, gets treated like dirt by several of his supposed friends, gets damaged quite a bit, and is one of the few wholly good characters in a setting of Grey and Grey Morality. Despite all of these hardships, he remains almost completely upbeat, never loses his sense of humor, and does his best to help anyone he can.
Magnificent Bastard: Megatron is back in form as this; he was pulling the strings behind pretty much everything that happened in season 1. Shockwave managed to outpace him in this department though.
Galvatron shows signs of this in issue 32, murdering General Witwicky, ridding himself of an "ally" who proved too willing to use force to keep Galvatron in line. Then blaming Prowl to manipulate the EDC into upholding their alliance.
Moral Event Horizon: Starscream murdering Metalhawk when no one was looking, then using his death to propel his own popularity and then win the population over to his side.
Bludgeon crosses it when he kills Varta.
Senator Proteus definitely crossed it after what he had done to poor Shockwave.
In-Universe, Soundwave seems to view Shockwave's Evil Plan as this, especially after he refuses to let Soundwave heal Megatron with Ore-14.
Galvatron murdering General Witwicky, then using his death to manipulate Marissa.
Narm: Deliberately done when Gorlam Prime is undergoing its devastation, and everything's coming apart and disintegrating at a molecular level, Jhiaxus proclaims his victory and makes an epic escape after the Titan. Monstructorů climbs on and straddles the ship like a kiddie ride. What was once a triumphantVillain Exit Stage Left has now been made positively adorable.
Narm Charm: The old school comic styled flashbacks in the annual would usually be Narmy, but they manage to work fantastically when combined with the modern sequences.
Exemplified in a flashback in issue 17 when he's testing Energon variants on a hapless Cybertronian, who freaking explodes. The comic cuts to a panel of Shockwave taking stock of this as hundreds of test subjects' corpses hang from the ceiling above. HOLY PRIMUS.
Issue #33 has a double doozy with the massive, offline hulks of Omega Supreme and the Superion suspended in Starscream's hangar. Superion is by far the worse of the two, having been so badly damaged one of his components is fatally injured and his spine is visible.
One-Scene Wonder: Barrel Roll only appears for one scene and dies in said scene, but comes off as one of the most sensible and likable Autobots.
Replacement Scrappy: Galvatron is an in-universe example. An issue of MTMTE strongly suggests that he's just a figurehead for Soundwave, and that if Megatron were to come back, the Decepticons would instantly fall back under his command.
To an extent, the IDW verion of Arcee. The original depiction of the character in Furman's run was widly disliked for being radically different from previous versions of the character. RID makes her a considerbly more likable and developed character, who isn't just defined as being constantly violent. Then she gets a cool upgrade, decides that Good Feels Good, and joins Optimus' team.
While still not popular, Spike Witwicky's general obnoxiousness is both toned down and widely mocked In-Universe, making him far more entertaining than he was previously.
Rewatch Bonus: With all the stuff that's revealed in issue 14 you'll slap yourself in the face for not noticing all the hints and foreshadowing. This applies to everything regarding Prowl, Bombshell and the Constructicons, the Dinobots' actions in issue 9, and the wilderness surrounding New Iacon.
The Scrappy: Metalhawk and the Nails (excluding Sky Byte, of course) since early-on their only purpose seemed to be making things more difficult for the Autobots and Decepticons. Their Holier Than Thou attitude and tendency towards Never My Fault didn't help, not to mention most of their screen-time is spent insulting the protagonists.
Bumblebee before Dark Cybertron due to him being an awful leader who spent more time whining, provoking his own allies, and letting Prowl stomp all over him than actually leading. Thankfully he was rescued at the end of season 1.
In season 2, Chromia seems to be taking over the status of Scrappy from Bee and Metalhawk due to being a massive Karma Houdini. She killed three people to try and get Windblade to return to Caminus. Other characters have avoided punishment for crimes, like Megatron or Prowl, but they at least suffer for their actions. Chromia is just let off the hook with a pinky promise that she won't kill people anymore. This got worse after issue 33, where she has the gall to insult Wheeljack before she even meets him.
Spike Witwicky is still this to many people, but then that's nothing new. To be fair, it's made very clear that nobody in-universe can stand him either.
So Bad, It's Good: Thundercracker's screenplay which has character names like "Josh Boyfriend", opens with a cheesy expository monologue about how hard life is, and has the characters constantly referring to themselves as "earth humans". Thundercracker thinks it's cinematic gold.
Take That, Scrappy!: Prowl pretty much blames Spike Witwicky, the much-hated Nominal Hero from Mike Costa's run, for making him into a cynical bastard. The mere thought of Spike pisses him off to no end. The Constructicons also despise him and make their dislike quite outspoken. The solicitations for Issue #36 run with this and is essentially a parade of Take Thats against Spike.
Bumblebee getting his head smashed in and Galvatron vaporizing the unpopular General Witwicky probably fall under this.
Tear Jerker: Shockwave and Soundwave's respective backstories.
The deaths of Bumblebee, Metalhawk, and ultimately even Shockwave.
They Wasted a Perfectly Good Plot: A minor example, but some fans felt that Starscream killing Metalhawk ruined a really interesting Redemption Quest character arc that the comic seemed to be building up to. Somewhat subverted due to a) the comic still portraying Starscream as somewhat pitiable even after this and hinting that he may be remorseful for the act, and b) Metalhawk coming back to give Starscream grief.
Vanilla Protagonist: Bumblebee is surrounded by a well-liked Cool Old Guy, a lovable Mad Scientist, a bot striving to find the best in people and make everyone equal, The Starscream who is trying to change, a former criminal trying to make a new life, the Big Good and his ragtag crew on a quest to stop a madman, and many other colorful characters. A generally agreed upon complaint in the comic is that Bumblebee is without a doubt the least interesting or likable character. While the entire story doesn't revolve around him like other examples, the audience is stuck with his POV as Autobot leader. And then he died.
Sometimes when you become the leader, these things happen.
Wangst: Bumblebee spends way more time feeling sorry for himself than he really should.
Win Back the Crowd: Maybe not to the extent of its sister series, but even so, it's generally agreed to be better than the predecessor to both. Its far stronger continuity is probably invaluable in this regard.
Season 2 seems to be attempting to do this for fans who felt that RID couldn't keep up with MTMTE in terms of quality. It's largely successful so far.
The Woobie: Shockwave, after we learn his gruesome origin. The bitterly ironic part is that the emotionally devoid scientist wouldn't say the same of himself.
Also, Dirge, who just wants to live his life in peace but keeps getting dragged back into conflicts he wants no part of.
Issue 28 does a very good job at making you feel bad for Cosmos. One of his first lines is commenting how miserable he feels because he abandoned the Lost Light crew based on the promise of a new life... which promptly lead to him getting shot at. Throughout the issue he makes multiple references to how lonely he is all the time.
Uncanny Valley: When Nova Prime snaps at Dai Atlas in the annual he's drawn with humanlike pupils and his normally soft yellow eyes suddenly become blood red. The result is... unsettling and serves as a small crack in Nova's apparent "knight in shining armor" persona.
The new artstyle being a mixture of Rescue Bots and Prime has slightly annoyed new viewers, while others are fine with it. The show's premise is also attracting some ire, with Bumblebee being the leader, while others think this could have some interesting storytelling possibilities.
The tone of the show being Lighter and Softer than Prime as well. Some are OK with it, feeling that Prime became too dark and serious at times. Others of course, liked the more serious approach and feel that making things too different in tone could set up a Mood Whiplash between the two series.
The Dinobot character having been revealed to be Grimlock has brought forth a whole bunch of mixed feelings. Among them his redesign lacking his traditional colours, as well as a new very different face to any prior versions of Grimlock and his personality is also clearly more comical than the warrior seen in Transformers: Fall of Cybertron. And then it was revealed he was a former Decepticon who crashed on the prison ship, that without an in-story explanation brings forth a whole bunch of Continuity Snarls to the Aligned universe that not even Broad Strokes would be able to solve fully. On the other hand, his redesign still has the same basic shape as most other incarnations of Grimlock, Grimlock's personality being somewhat comical is not something that has never happened before in the franchise, fans were already coming up with theories to help his last Aligned appearance make sense with this one, and there are fans who simply love the audacity that in a series titled Robots In Disguise (with Bumblebee even making it verbally clear they need to have them), that Grimlock is part of the team with his Dinobot form completely exposed.
The new animal-themed Decepticons are either visually interesting and quirky, or completely ridiculous even or perhaps especially by the standards of other Transformers with Beast forms. Bisk in particular. He has people who find him entertaining, whilst others have already started comparing him to Jar JarBinks. And then there's Thunderhoof, who is either Crazy Awesome by virtue of being a robot with giant moose antlers that turns into a combine harvester, with said antlers turning into the vehicle's harvesting claw, or an utterly ridiculous disgrace with a name that sounds like a bad MLP OC.
And then, there's Drift— some are unhappy that he (a notable Base Breaker character in and of himself) has been getting a ton of exposure lately (first in the films, and now in RID), while others think his new samurai-themed design and Minicon partners are cool. Still others— mostly fans of More Than Meets the Eye— are upset that he's not exactly like his IDW design, seemingly taking more cues from the live-action movie version instead.
Airazor and Slipstream being in the series as male characters, not helped by the general lack of female characters (Transformers Prime also had very few female characters, but the use of Airazor and Slipstream as names for males seems to be the main cause of the brokenness—never mind that the characters in question are Minicons, glorified accessories who rarely have much in the way of personality, and are known for reusing names from more distinctive characters), nor likely Transformers: War for Cybertron (set in the same universe) featuring a version of the latter that was more true to her namesake.
Epileptic Trees: Grimlock being revealed as a former Decepticon in this series with a different personality and appearance to what he's had prior has made it so that a number of theories regarding this change have started to sprout up before any official reason has been revealed, including potential memory loss and forced rebranding.
The release of several official character profiles from Hasbro Studios has only further confused matters— Grimlock's profile seems to put paid to the whole "former Decepticon" thing by saying that he was unjustly imprisoned, but it also mentions that he was locked up "eons ago". Which brings into question just how much time has elapsed between Prime and this series, among other things.
