Usually very serious real issues are only invoked if you think you have the skill and craft to deal with them, and are willing to deal with them and are not using them as a gimmick to further your story. These issues bring up stories all of their own and change narrative. If you don't fully understand and appreciate these things but still invoke these serious issues then your work comes off as tacky and unaware.
Anyone remember the movie Running Scared from 2006? There was a scene where this kid was abducted by two wack job pseudo-parent types who take him back to their very own 'disneyland.'
