Jim: Hey, you leave me alone. Just get out of here and leave me alone.
Madame Leota: Oh, I see. You're just going to sit there, feeling sorry for yourself.
Jim: Tell me why not. This whole thing was my fault. We should've never been here in the first place. Supposed to be at the lake. We'd be sitting by a warm fire right now. And I made us come here. And now it's too late.
Madame Leota: No. It's never too late.
Jim: Hey, look, I tried to get in there, and I can't, all right? I tried! I failed!
Madame Leota: You try. You fail. You try. You fail. But the only true failure is when you stop trying.
Jim: What do you want me to do? Huh?
Madame Leota:...Try again. (cut to Jim, behind the wheel of his car, preparing to plough through the mansion wall)
Jim successfully rescuing his kids against the animated suits of armour.
Michael getting over his fear of spiders to open the mausoleum door.
That Jim manages to keep calm enough not to shout but try and talk him through it, even though he and Megan are in a way scarier situation.
Mystic Manor itself. While extremely different from all other Mansions it has amazing special effects and really conveys a magical atmosphere. Bonus: Danny Elfman did the music for the ride!
The Hatbox Ghost's return to the mansion after decades as a park legend. He went from "removed because they couldn't get the gag to work" to one of the most impressive effects in the entire ride.
Vincent Price recorded an entire narration soundtrack for Phantom Manor, but nearly all of it was replaced by a French-language dub. "Nearly", because the one thing no one was willing to part with was the absolutely iconicEvil Laugh he gave Ravenwood.
