I remember this movie from when I was like 7. All I remember is there was this treehouse that was off limits to this little boy who was visiting his grandpa, and every time the camera went to the treehouse this creepy music played. And at the end the boy was running away from his grandfather for some reason and climbed up the treehouse and the grandpa ran after him and the ladder broke and the grandpa had to go to the hospital. Familiar to anyone??
