ghost graduation
The blurb for this Spanish movie made it seem like it would be a silly fun ghost story. And it was, but it was also touching. A teacher is hired at a high school because of his ability to see and speak to ghosts who are causing trouble.

 
It started out silly, but by the end, it was a ghost version of The Breakfast Club. Very fun. Go and check it out.
