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.
The comic book. As Jim Butcher himself points out, Dresden Files has the heart and soul of a comic book anyway.
The roleplaying game is both incredibly faithful to the books, condensing the Dresdenverse into a very elegant and functional game, and flexible enough to handle anything you might want to do with the game. An example is how a couple of people in one playtest group wanted to play as a ghost and a ghoul. They managed to figure out how to do so after about 10 min of planning for each.
One of the other playtester groups succeeded in making a character who was essentially an animated sentient whip.
Crazy Awesome: In Ghost Story, Harry was able to manifest his disembodied spirit into the real world and punch a mook, specifically because he was insane, which is the very definition of this trope. Recall that only insane ghostly spirits can manifest physically, because it's incredibly dangerous. Oh, and the way he comes to realize he's crazy enough to do this? He remembers all the other crazy stuff he's done in previous books. And much of that crazy stuff was awesome.
While this might not count as a true crowning moment, I'd say that at the very least, Harry qualifies for father of year. Let's look at the facts. From the moment he finds out that he has an eight year-old daughter that he never knew even existed, he is prepared to go to the wall and do whatever it takes to make sure that she's safe. This is a girl that he never even knew existed, much less met. When you compare that to how many fathers have lived with their children for their several years and couldn't give two shits about them, this becomes extremely awesome.
Harry: "If the world burns, so be it. Me and the kid will roast some marshmallows."
Crowning Moment of Heartwarming: From "Gentleman" Johnny Marcone, of all people, with the girl who took a bullet for him. He even goes so far as to steal the freaking Shroud of Turin to try to heal her.
Another one from Lasciel's shadow in White Night.
Lash: "I... she doesn't deserve you."
From Dead Beat:
"You're the one they arrested in the nursery a few years back," he said. "You broke in during a blackout. They found you in the middle of a wrecked room with all those babies."
I took a deep breath. "Yeah."
Lamar was silent for a second. Then he said, "You know that the year before, the SIDS rate there was the highest in the nation? They averaged one case every ten days. No one could explain it."
"I didn't know that," I said.
"Since they arrested you there, they haven't lost one," he said. He turned back to me. "You did something."
For clarification, when you realize that Harry has been suffering from Being Good Sucks this whole series, and keeps at it anyway, having someone notice that he made a positive difference and help him because of that is huge.
Crowning Music of Awesome: Ride of the Valkyries. Also tells you something about Gard's sense of humor considering what the short story "Heorot" reveals about her true nature.
And in Cold Days: "We will, we will, rock you!"
Edible Ammunition: If you agree that every random thing that the Entropy Curse used from its environment to kill its victim may get called its "ammo", then yes, chalk up one unlucky vampire dying from cold turkey.
Evil Is Sexy: Lara Raith is pretty much the embodiment of this, as are all the other Raiths, and both Fairy Courts, and Bianca and many of the Red Court vampires (before seeing their true form at least). Harry even mentions the benefits of having no hot water as taking cold showers constantly is a good defense against the supernatural charms of the dangerous female beings he meets constantly.
The Goodship Molly Dresden has a substantial fan following too.
Foe Yay: Harry and Marcone seem to have a little of this going at times.
Harry and Lara have plenty of these whenever they meet or team up.
"Funny Aneurysm" Moment: The short story "Day Off", found in the anthology Blood Lite, features the characters of Kirby and Andi, the fact that they are going steady, and the fact that Harry is in a relationship with Warden Captain Luccio. In the book Turn Coat, Kirby dies and Harry and Luccio are told that their relationship was psychically arranged by the same Council traitor who killed LaFortier and Morgan. Consider the difference in tone between the two stories and you have got Mood Whiplash as well.
Growing the Beard: The first two books are okay, but the series really hits its stride at Grave Peril. It improves even more during and after Dead Beat.
Butcher really hit his stride when he had Harry punch a werewolf through a goddamn wall. After that the series figured out its pattern of stringing together incredibly awesome scenes with interesting mysteries and witty dialogue.
Butcher himself lampshaded this when he made a statement to the effect that one of his regrets about the Dresden series is that people have to start it by reading the books he wrote when young and inexperienced.
Harsher in Hindsight: From "Changes". "If that was the price I had to pay to make my daughter safe, so be it. If I was haunted by my choices for the rest of my life because Maggie needed me to make hard choices, so be it." This passage is from when he was deciding to kill Lloyd Slate and become the Winter Knight. Applied to what happened later, when he killed Susan, there is a whole new dimension of haunting regret.
Another one occurs in Grave Peril, when Harry is waiting for Susan to bail him out of jail and sees Michael and Charity talkling he finds himself wondering why alll his relationships don't work and jokingly puts it down to all the "ghosts, demons and Human Sacrifice." cue Changes...
In the short story "Something Borrowed", Kirby was supposed to be Billy's best man at his wedding, but got really hurt in a fight the night before (no thanks to the jello shots)... Flash forward to Turn Coat...
In Death Masks, when Harry tracks Marcone to Persephone's bedside, he assumes the comatose girl must be Marcone's own child. He tries to keep up his hatred for the gang boss because of his many crimes, but a part of Harry can't help but think he might have become every bit as unscrupulously-ruthless himself, if he'd had a daughter who was helpless and needed him to fight for her. Several books later, Changes comes along...
Hilarious in Hindsight: In Backup, Thomas says that Harry and e-mails go together like Robert Downey Jr. and sobriety. Turns out, RDJ is AWESOME sober.
Ho Yay: Harry and Thomas. Even though they're half-brothers. Half-BroYay!. Hell's bells, the Ho Yay actually becomes a plot point at times.
Marcone is constantly getting people that hate him to do what he wants, even when they are perfectly aware that, lesser or no, he is evil.
Martin, in Changes.
Collin Murphy scams Uriel Wow.
Offscreen Moment of Awesome: An unfortunate result of the books being told from Harry's POV is that we miss some of the crazier fights in the background, like the battle between the Wardens and the Red Court across half of Europe in Dead Beat or Morgan and Michael and half of Summer trouncing the Red Court in Proven Guilty.
Add to the list Molly, Thomas and Mouse fighting the Ick in Changes while Harry lies broken on the other side of a house.
The Oblivion War, as specified in Backup. Jim Butcher even said that by Harry's very nature, he'd be an immense liability if he even knew about the war.
Small Favor had what was likely an awesome parkour chase as a gaggle of faerie elves chased Thomas-disguised-as-Harry across the Chicago rooftops. We missed it mostly because Harry was with Michael as he went Fist of God on a few hundred hobs in the subway.
Between Changes and Ghost Story, Murphy killed two warlocks who were at Council-tier strength. Considering Murphy is a human with no magic to her, that is really impressive, but we sadly don't get to see it.
One-Scene Wonder: Ferrovax. He's only shown up at the party in Grave Peril, and did comparatively little there. He's also one of the most popular characters among fans.
Comparatively little being flattening a man with the tone of his voice.
Sue, the Tyrannosaurus Rex that Harry revives in Dead Beat.
Paranoia Fuel: Lasciel's shadow can make illusions so perfect that Harry can not tell the difference. She completely makes up a person to interact with him, and he is so taken in that other people start thinking he has gone nuts because he is talking to empty air. Then she demonstrates that if she wanted, she could use this to kill him at any time. Yeeeesh.
Stoic Woobie: At the end of Cold Days, Mab certainly counts. Her daughter Maeve, was possessed by Nemesis and threatening to destroy the world, was killed before her eyes, and by Maeve's actions her second daughter has become the Summer Lady, keeping her from Sarissa and destroying the relationship of BFFs they had previously. The only hint we get of her deeper turmoil is when she admits to Harry who asked if she didn't like her choice to have Maeve killed, "[she] was mortal once."
Cat Sith, introduced as an uber Badassmalk, he ends up possessed by Nemesis. Even if he survived his fight with Harry, Nemesis appears to have destroyed his mind and taken over him completely. Ironically this is noted as lessening Sith's badass-ness in the process.
Unfortunate Implications: The repeated sexualization of women, to some; Harry has a tendency to describe attractive women in extended detail whenever he meets them, going on page-long monologues in some cases. On the other hand, the series possesses a number of non-sexualized women note (Meryl, Helen Beckett, Luccio's original body, Martha Libery, Ancient Mai, Anna Ash and most of the Ordo Lebes, the Mothers, and more) and many of the jaw-droppingly beautiful women who earn page-long monologues are fairies, White Court vampires, or monsters wearing a facade of beauty. Also, Harry's fixation is presented as a character flaw that gets him into trouble (i.e. unintentionally pulling his punches when he's fighting Aurora) and his sexual urges become a serious problem in Cold Days where the mantle of the Winter Knight is repeatedly amplifying it to the point that he has the urge to rape several women he meets, much to his horror. It's also worth noting that this is clearly a deliberate flaw put in by Jim Butcher and not a result of the author's own tendencies. In other books written from John Marcone, Murphy and even Thomas's point of view the Purple Prose is completely absent.
The Woobie: Both Harry and Thomas. The universe clearly hates their family.
By the end of Cold Days Titania admits she knew Aurora was corrupted and needed to be stopped from destroying the world. She had to watch as Harry killed her only daughter and knew it was for the best. Then she forced to take up raising young Lily to her position as Summer Lady. And just after ten years of Lily's reign, the thing that led to Aurora's death led to Lily's death. She must now raise Mab's daughter Sarissa to be the Summer Lady.
Lily did not want to become the Summer Lady. She wanted to become human, find a husband, and raise a family. But because of circumstances beyond her control, she was forced to become the Summer Lady. Then she was manipulated by a corrupted Maeve to thinking she was The Hero who could help save the world from Outsiders and followed Maeve into an attack that would have led to the destruction of the world.
And now Sarissa has taken her place, meaning that she'll have to spend the rest of her life working to oppose her own mother, as well as any friends she might possibly have had in Winter. (Hey, it can happen.) Maybe even be obligated to kill some of them on the battlefield if the Courts should come to blows again.
Little Maggie, so so much. She's never said a word on-page as of Cold Days, yet one can't help but want to hug a little kid who's seen her foster family massacred, been a captive of Red Court vampires, witnessed perhaps hundreds of preparatory human sacrifices, and who may or may not have seen her mother transforming into a monster and then having her throat cut by her father.
The TV series provides examples of:
Broken Base: The fandom is vehemently torn over whether Book Bob is better than TV Bob, and generally over whether the show is a good adaptation of the books.
Fan Dumb: The people who dislike the show can cross into this, to the point where Jim Butcher calls them out on it.
