Heartwarming / Casper

• As creepy as it may be to some, Casper saying "Can I keep you?" to Kat is his way of saying that he hopes they'll always be friends. You can see the innocence and wonder in his big baby eyes as he says it, because after all this time he finally has someone he considers a real friend.
• The scene where Casper meets Amelia, who tells him that not only is she proud of him for giving up his chance to be resurrected by using the Lazarus to bring James Back from the Dead for Kat, but Casper's father is proud of him as well. And Casper gets to have his wish as well as a reward, even if it was only temporary. It's no wonder why the film has gone down as a Halloween fairy tale.
  Amelia: That was a very noble thing you did tonight, Casper. I know Kat will never forget it. She needs her father. And I know yours will never forget it either. You fulfilled his greatest dream, Casper, and I know he is very, very, proud of you. And for what you've done, I'm giving you your dream in return. But, it's just for tonight. Sort of a Cinderella deal.
  Casper: So I have until midnight?
  Amelia: [smirking] Ten.
  Casper: Hey, Cinderella got until midnight!
  Amelia: [smiles] Cinderella wasn't twelve years old.
• Casper and Kat slow dance at the Halloween party. Casper ends up uttering his "Can I keep you?" again, which Kat recognizes, and that's how she knows it's him; even before that moment, her facial expressions indicate she recognizes him on some level. Casper and Kat even get to share their first kiss, just before he turns back into a ghost.
• Casper and Kat bonding over the course of the movie, with Kat finding kinship in another (literal) troubled soul, and Casper finally meeting someone who (ultimately) isn't afraid of him, obtaining a new friend as a result.
• At the end of the movie, the Ghostly Trio keep their promise to James and find Amelia. Considering they've been nothing but jerks throughout the entire movie, they really Took a Level in Kindness in doing this.
  James: How?
  Amelia: Let's just say you know three crazy ghosts who kept their word.
  • There's also them scaring away Vic and Amber, who were about to crash Kat's party, although this was probably them getting a good scare out of it rather than wanting to help Kat. But when you consider they didn't go and crash the party themselves...
• The reason Amelia herself isn't a ghost: James and Kat loved her so much when she was alive (and continued to love her long after her death) that she was able to pass on peacefully and happily, with no "unfinished business" to take care of.
  • Also, the Ghostly Trio bonding with James and, despite being constant jerks, trying to cheer him up with a couple of drinks. As mentioned before, they even locate his deceased wife for him as part of a promise.
• In its own creepy way, the Ghostly Trio deciding they want to make James into a ghost so he can hang out with them and be their friend forever... and then, moments later, deciding they like him too much to kill him themselves.
• Even though the circumstances behind it are tragic, the fact Casper's father spent the rest of his days trying to restore his son to life is a testament to the man's devotion. Knowing he did everything in his power is probably why he was able to pass on.
