Ghost Messenger (Korean animated movie)

1. ~6:30 before title is shown
2. So the child is living with his grandfather?
3. ~22:40 So the mother disappeared into some trap?
4. 34:00 Is Grandpa even real?
5. 41:45 The guy's arm heals/reappears.
6. ~50:10 So the child and his mother are shamans?  Is Grandpa a ghost?
7. ~54:00 So Grandpa *was* some sort of spirit.

• So, apparently, this movie is an extended commercial for a Korean comic book.  Because of that, I am rating this at 8/11; I would otherwise might have rated this at 10/11. 
  
  I was wrong.
