Audience-Alienating Premise: Many fans of previous Ghost Riders seemed to be turned-off by Robbie Reyes's design, him being a teenager, driving a car instead of a bike, and listening to electronic music (Ghost Rider is usually associated with rock and metal). People who were excited about his book fear it might have had a negative impact on the sales, and even Marvel editor Tom Brevoort, the series's biggest cheerleader, expressed worry that Robbie might become a Replacement Scrappy.
Ketch or Blaze. Ketch fans consider the original Blaze comics to be absurdly dated and hackneyed while the Ketch run slightly more evergreen, at least, in its first 25 issues. Blaze fans meanwhile hate Ketch's run for being too 90s extreme, Danny himself being a bland Decoy Protagonist with little to no agency besides serving as host body of the second GR (the actual protagonist), plots that largely consist of mystery hooks surrounding the identity of Ketch's Spirit of Vengeance (most of which led to nowhere), and Howard Mackie's poor writing in general. There's also a third group who view the first two eras as both flawed and badly outdated in their own ways, and that a truly "timeless" GR series is yet to be produced.
Jason Aaron's take on the character in the 00s. Besides furthering Garth Ennis's transplanting of Danny Ketch's visual onto Johnny Blaze, it jetisoned pretty much all existing lore from Blaze, Ketch, Zarathos, and the franchise in general and replacing it with the Black Ops Angels, conspiracies and counter conspiracies and deep cover Angels pretending to be demons and pretty much made the Ghost Rider mythos overly complicated and convoluted. Others, however, like the more complicated take balanced by the grounded characterisation.
Robbie Reyes' series. Some like his series for its grounded look at urban gangs that is different from usual Ghost Rider fair and has a likeable supporting cast. Others dislike how it barely focuses on the supernatural and feels disconnected from the Ghost Rider mythos.
Creepy Awesome: A flaming skeleton biker with a chain that can burn the souls of evil doers? Hell YES!!!
Crossing the Line Twice: Black humor is quite common for Spirits of Vengeance. Jason Aaron's series was basically oozing with it. For example, Johnny meets a witch called Skinbender, who submits everything around her to incredible amounts of Body Horror. Horrifying, right? She also looks like Sailor Venus? Hilarious.
Friendly Fandoms: Ghost Rider fans were always on good terms with fans of more horror-oriented Marvel characters, like Blade or Man-Thing and, to a lesser extent, Doctor Strange. Robbie meanwhile was embraced by teen Marvel fandom, with fans of Ms. Marvel, Young Avengers and Runaways seeming to be especially fond of him.
Hilarious in Hindsight: The name Noble Kale. "Boy, those sure are some virtuous leafy greens!"
Jerkass Woobie: Caleb may be a jerk and a killer, but given what happened to him, it's a bit understandable.
Memetic Loser: The Penance Stare has failed (in admittedly kind of humiliating and nonsensical ways) a few times, but from the way people talk about it you get the impression that it only ever fails and is little more than a Fake Special Attack that only ever gets trotted out when writers want to showcase how badass a character is by subjecting Ghost Rider to The Worf Effect. The fandom perception got so bad that Marvel eventually introduced the more potent and powerful Damnation Stare variant (starting with the King of Hell story arc), which retains its effectiveness even against enemies that the Penance Stare has failed at, albeit at the cost of damaging Ghost Rider's mind as well and thus limiting its usage for emergency situations.
Never Live It Down: Mephisto is Ghost Rider's Arch-Nemesis... but if you ask your average comic reader, all they'll know him for is taking Peter Parker's marriage in One More Day, to the point that you'd think that's all he does.
Obvious Judas: Anton Satan was initially portrayed as an ally of sorts. He also happened to be a self-proclaimed Anti-Christ. Of course he was going to be a treacherous scumbag!
Older Than They Think: The idea of a Ghost Rider driving a car isn't as new as you might think. When establishing Spirits of Vengeance as a part of an ancient legacy, Jason Aaron included a duo of Ghost Riders riding a car and truck, as an Affectionate Parody of Smokey and the Bandit.
Replacement Scrappy: Alejandra Jones from the very short lived 2011 series became widely reviled almost immediately after her debut issue, thanks in no small part to her obnoxious and thoroughly unpleasant characterization, on top of being an Idiot Hero who brought more trouble than help. Readers turned away in droves, and her comic never even made it to the double digits before getting unceremoniously cancelled after nine issues, with Alejandra herself fading into obscurity as a result.
Squick: More recent series are filled with it. As was the miniseries Trail of Tears. It featured a pair of outlaws that the Ghost Rider killed by smashing them together so hard they fused together. They came back as minions of Hell, still fused together.
