- Alas, Poor Villain: Though Vic played along with Amber's scheme, he was clearly against the idea from the start. In turn, it's easy to wish he had somehow avoided the comeuppance at the end of the movie.
- Awesome Music:
- Ass Pull: The reveal that Casper died at the age of twelve. Considering how he was portrayed as an eight year old throughout the movie, it makes it obvious the writers made him closer to Kat's age (thirteen) at the last minute so his romantic feelings for her would be genuine rather than a Precocious Crush.
- Big-Lipped Alligator Moment: The particularly odd scene where the Ghostly Trio goes inside Dr. Harvey and changes him into Clint Eastwood, Rodney Dangerfield, Mel Gibson, and the Crypt Keeper. It is never mentioned again throughout the rest of the film, nor do the trio ever use their apparent morphing-abilities again.
- Broken Base: The "can I keep you?" line from Casper to Kat as she's falling asleep. Some find it creepy and a little perverted, given that he kisses her while she's barely conscious. Others are more okay with it, since the movie treats his attraction to Kat as a Precocious Crush and he is eternally twelve years old.note For what it's worth, him saying that in human form is what tells Kat that it's him - so she must seem to remember him saying it and appears to be okay with it.
- Evil Is Sexy: Carrigan being played by Cathy Moriarty. Her ghost form takes it even more so.
- Hilarious in Hindsight:
- Devon Sawa plays Casper's human form. Years later, he spends an entire movie trying to cheat death.
- In the pilot of Extreme Ghostbusters, Egon reluctantly breaks, in his own words, "the first rule of ghostbusting: never go solo." Sure enough, he's defeated. The same happened to Ray here.
- The film was made by Universal, whose parent company MCA had a 20% stake in Casper rights-holder Harvey Comics at the time. 21 years later, Universal's current parent, Comcast NBCUniversal, bought DreamWorks Animation, who currently owns the Harvey Comics archives. Therefore, Universal now owns Casper the Friendly Ghost!
- Dr. Harvey thinks he needs to have The Talk with Kat, and she assures him it's "not that late". Then comes Christina Ricci's very sexual roles in The Ice Storm and The Opposite of Sex - which she did to break out of her child star image.
- One scene has Dr. Harvey catch the Ghostly Trio with a red vacuum cleaner.
- Memetic Molester: Casper's "Can I keep you?" is often taken out of context and used to portray him as a pervy stalker.
- Memetic Mutation: Ray Stantz's cameo line "Who you gonna call?...Someone else." has become a very popular phrase for dissing the 2016 reboot of Ghostbusters.
- Moral Event Horizon:
- Carrigan crosses this when she and Dibs steal the serum that can return them to life if they're killed, then tries to kill Dibs so he can steal the treasure from the vault as a ghost. She attempts this first with an axe, then with her Range Rover. Her attempts to kill him both fail and she ends up dying instead, but the fact that she tried twice to kill him just to get rich counts.
- Dibs crosses this when he betrays Carrigan by stealing the serum and the treasure for himself, refusing to revive her.
- Nightmare Fuel: The Ghostly Trio's first impression can be terrifying. Double for the way they scared Dr. Harvey, which also counts as a Funny Moment. The bathroom mirror scene deserves special mention, especially when The Crypt Keeper appears out of nowhere.
- One-Scene Wonder: Ben Stein, who else?, as the deadpan lawyer reading the will early in the film. Also, the hilarious cameos of Don Novello's Father Guido Sarducci and Dan Aykroyd's ghostbusting Raymond Stantz.
- No Problem with Licensed Games: The SNES/Famicom game is actually pretty fun and creative, playing like a modified version of A Boy and His Blob. Casper takes various forms to escort Kat through his house down to the Lazarus Machine, fighting off his uncles and Carrie along the way. Only problem is that it came out at the end of the SNES lifespan, so cartridges are rare and super-expensive.
- Special Effects Failure:
- In the first film, when the Ghostly Trio eat. The food they shove into their mouths are just as animated as they are.
- The scene where Father Guido Sarducci has his head twisted around hasn't aged well.
- In the sequels, the ghosts have robotic movements, are animated choppily, and face-plant smack in the middle of the Uncanny Valley.
- They Wasted a Perfectly Good Plot: Some people hold this reaction towards the film, feeling that it could've been much better if it had cut out all of the other sub-plots and focused solely on the relationship between Casper and Kat, with Dr. Harvey's interactions with the Ghostly Trio being the main source of comic relief.
- Visual Effects of Awesome: Say what you will about the rest of the film, but even after twenty years of technological development, the computer animated ghosts are still very convincing. It helps that animated ghosts are very well-suited to the CGI capabilities of 1995; they float in the air, they don't have shadows, they don't have reflections, etc.
- WTH, Costuming Department?: When we finally see Casper as a living boy, he's dressed like a bishounen pirate.note
YMMV / Casper
