I saw the movie in the early 90s, English language, and in color. I watched it on TV, but I believe it was a feature film.
The ending involved a young boy, probably 8-10 years old, walking around a burnt out house. I think there were firefighters walking around in full gear, ignoring the boy. The house was burned enough that it was exposed to the outside. I don’t know if his family was dead or simply gone, but he was apparently left alone after returning from some adventure. I believe the whole movie had a somber, sad tone and may have been a fantasy in line with the Jim Henson movies of that time period (Dark Crystal, Labyrinth, etc).
Unfortunately I cannot remember anything else about the plot or characters. Any help is much appreciated. This has been bothering me for at least 15 years.
