I'm looking for a movie of some boy stuck in a treehouse when a girl passes by and they start talking and hanging out. He eventually tried to convince the girl to go to "purgatory" or something where he tries to trade positions with the girl and at the last moment he goes to hell through the floor under him
Some details
Here's everything you mentioned, pulled together:
- It's a movie
- I think it's from the 2000s or later
- The girl walks by a treehouse in the neighborhood and sees the boy
- It's a basic treehouse
- The boy can only exist in or around the treehouse, and possibly the house on the property too?
- The boy is friendly with the girl at first, but he's actually trying to switch places with her
- They befriend each other
- The boy killed his parents and then himself in the treehouse so that's why he can't leave
- His spirit/ghost is stuck there
- He eventually takes the girl to purgatory (or like it?)
- Purgatory looks like booths — like a bank or ticket counter — with people behind each booth
- The girl almost switches places with the boy
- She's convinced not to go through with it (forgot how)
- Hell appears as a hole that opens up under him in the floor
- The boy doesn't want to go to hell
- The girl was about to go for him but was talked out of it
- He goes to hell instead
- Both kids are in their late teens or 20s
