* EarWorm: The main theme: "''Ghoooostwritaaaah! '''Word!'''''"
* EnsembleDarkhorse: Victor, Rob's friend in "Building Bridges," seems to be very popular in the fandom. The producers must have noticed because he shows up in another episode despite not being particularly involved in the plot.
** Calvin Ferguson, both with those who LoveToHate him and those who [[RootingForTheEmpire root for him]].
* {{Fanon}}: One of the leading theories about Ghostwriter is that he's the ghost of Jamal's great-grandfather Ezra.
* FanonDiscontinuity: To most fans, The New Ghostwriter Mysteries never existed.
* FoeYay: When Calvin tries to convince Rob [[WeCanRuleTogether to join forces with him]], it sounds like he's hitting on him.
-->"You're the strong, silent type. I like that."
** Alex even mocks Calvin afterwards:
--->"Did you actually think that Rob would hook up with you?"
* HilariousInHindsight:
** There actually is a show called ''Galaxy Girl'' (well, ''Galaxy Girls'') in development by LaurenFaust.
** To Catch a Creep parodies how politicians ran smear campaigns in elections in the United States. Smear campaigns have worsened since the early 1990's. [[RuleOfCautiousEditingJudgment Let's leave it at that.]]
** In Episode 2 of Into the Comics, Jamal looks at a yearbook, and comments how people dress out of date quickly. Ghostwriter is definitely a UnintentionalPeriodPiece from the 1990s.
--->Jamal: "Man, I wonder how people can look so out of date, so fast."
* HoYay: Hector has a pretty blatant crush on Avatar, the male makeup artist, when the team appears in Lenni's music video.
** Not to mention the guy himself. He's a ''male makeup artist,'' and he calls himself "The Fabulous Avatar."
** In "Lost in Brooklyn, Part 1" Tina meets Safira, visiting from Mozambique. Everyone does rush to see who it is coming to school in a limo, but Tina's the only one who takes one look and says "Oh, ''wow!''" when Safira gets out of the car.[softreturn][softreturn]By the time we cut to the classroom, everyone else has moved on, but we have Tina looking around the room until Safira is introduced by the teacher, whereupon Tina watches Safira's every movement with a smile until she sits down next to her, while everyone else acts normal. When she gets to say more than hi, she talks fast and rambly, and at one point talks about trying talking to her (a second pitch at being in her video, actually) with lines that sounded like someone trying to ask out a crush.[softreturn][softreturn]The entire first part is driven by her ''need'' to get this girl to be friends with her, and there's master plans and talk of "destiny" that she wound up sitting next to her and on and on and it ''doesn't'' end up having to do with the video. There ends up being a picnic in the woods on a blanket, and a DeathGlare at Safira's dad until he leaves. The mystery of the arc is introduced only in the closing moments of part one; the rest is ''entirely'' Tina positively drooling over this girl and stopping at nothing to get her attention. (Well, that and a few minutes devoted to Hector's introduction, setting up [[PutOnABus Rob's replacement]].)
* JerkassWoobie: Many of the villains are so pathetic that it's pretty easy to feel sorry for them. A good example is Manny Gite from "Into the Comics". He was an awkward twentysomething who lived with his aunt and desperately wanted to be a cartoonist. In an attempt to acheive this, he enters a contest for kids (in which the prize was getting to be in a comic book) disguised as his cartoon character Stoopdude and tries to sabatoge the other contestants.
* KarmaHoudini: Played With regarding Manfred Gite from "Into the Comics". Whereas most villains were taken away by the police or punished severely in the end, Manfred [[spoiler:is simply escorted away from the contest grounds after the Ghostwriter gang thwarts him. What kind of punishment Manfred got after that [[LeftHanging was never revealed]]. It's implied that if nothing else, Manfred's aunt was prepared to [[TheReasonYouSuckSpeech chew him out]].]] Considering some of the antics he pulled were illegal, that should have landed him in jail.
* MemeticMutation: [[{{Hackette}} Julia Stiles]]: "[[WebComic/{{XKCD}} Do you know anything about hackers? Can you jam with the console cowboys in]] {{Cyberspace}}? Ever read Literature/{{Neuromancer}}? Ever experienced the {{New Wave|Music}}? Next wave? Dreamwave? or {{Cyberpunk}}!?"
* SugarWiki/MomentOfAwesome: Rob snapping at Gaby, Alex, Tina and Lenni to [[BigShutUp shut up]] in "Get the Message Part 3" when they're arguing in the park in the aftermath of the accident earlier in the episode. He really came out of his shell. It's a pity [[PutOnABus he had to move to Australia.]]
** Frank tackling the villain who's getting away from the police in "Just in Time."
* NightmareFuel: Gooey Gus.
* {{Padding}}: Take away the slow typing and writing sequences and [[CaptainObvious obvious explanations]], and most of the arcs can be reduced by one episode.
* ReplacementScrappy: For some, Hector replacing Rob on the team.
* TearJerker:
** Calvin was a {{Jerkass}} but his devastation at losing his beloved parrot is pretty sad, especially for people who have also experienced the death of a pet.
** Alex's friend Kevin selling his deceased grandfather's basketball trophy (his prized possession) to pay for his drug habit.
** How badly Jamal and Rob take the possibility of [[TrueCompanions the Ghostwriter Team]] breaking up in the "Get the Message" arc. Particularly Rob since it's heavily implied that the Team are [[IJustWantToHaveFriends his first friends in a while]]. Then Rob gets hit ''again'' when his dad [[PutOnABus transfers the family to Australia.]]
** Examples from the books
*** In the book "Steer Clear of Haunted Hill", Alex and Leni's reactions to their loved ones (Gabby and Max respectively) having disappeared is positively heartbreaking. The disappearance of Rob isn't any better and might be worse from a Meta standpoint since this wasn't his LeeroyJenkins getting him in trouble; it was him being TooCleverByHalf [[spoiler: by refusing to buy that the crooks he ran into were actually ghosts (they weren't but that's not the point)]].
*** In the book where Alex gets kidnapped in the middle of a magic show, Gabby tearfully blames herself, in part because she and Alex had been bickering incessantly before the incident and also because she got the attention of the 2 stars who Alex witnessed arguing (they were among the main suspects and hadn't noticed Alex until Gabby yelled at him).
* WhatDoYouMeanItsForKids: Ghostwriter is a PBS learning show aimed for tweens.
