* BrokenBase: Opinions from the fanbase are split around this installment, some fans found it a major improvement over the theatrical live actions with a better mystery and less jerkish characterizations for the main gang, other fans find it a cheap-looking disaster that lacks the cast and humor of the theatrical movies. Likewise, opinions on the cast go from "surprisingly decent" to "something out of a bad fanfilm", although Music/HayleyKiyoko is almost universally considered to have done a good job.
* SugarWiki/FunnyMoments: During the fight in the bus, Velma and Daphne starts hitting their bags on the fat jock (the former because he inadvertently destroyed Velma's project). However, Fred landed on top of the fat jock, so they're frantically hitting ''him'' instead.
-->'''Fred:''' There's metal in the purse!
* FridgeLogic: The whole point of the Scooby-Doo series was the Mystery Gang going out to prove that the supernatural, specifically ghosts, weren't real and were just people in costumes. This movie pretty much negates that premise by having the gang's first adventure involve very real ghosts.
** Of course, this could also lead into a kind of FridgeBrilliance; none of the "ghosts" the gang faces resemble said very real ghosts so they lean towards a "this can't be real" mind set.
*** This could be also why Scooby and Shaggy are always afraid, since the "ghosts" might be the real thing.
* HeartwarmingInHindsight: Velma is played by “Queen of the Gays” icon Music/HayleyKiyoko, who at the time wasn’t out yet [[https://twitter.com/hayleykiyoko/status/1577416166016176133 but wondered if the casting directors knew]] and were implying Velma’s orientation. Velma herself was revealed as a lesbian in ''WesternAnimation/TrickOrTreatScoobyDoo''.
* JustHereForGodzilla: In a similar manner to Creator/MatthewLillard's Shaggy in the theatrical movies, some fans only check the movie for Music/HayleyKiyoko's Velma.
* RetroactiveRecognition: [[Music/HayleyKiyoko Lesbian Jesus]] as Velma?!
