YMMV / Ghostlight

• Complete Monster: Captain Nicholas Viker is a wicked ghost who seeks to make himself supreme over both the living and the dead. A bloodthirsty soldier in life who was killed after murdering his general, Viker spends decades devouring other ghosts to grow in strength so as to harm the living, his reign of terror only ended by the efforts of Keeper Strand and his daughter Rebecca, though not before Viker murdered them and devoured the former's ghost. Reemerging in the present, Viker sets about devouring any ghosts he comes across, including that of a 4-year-old girl, while seeking the power of the ghostlight, even threatening to devour Gabe's father to force him to hand it over, following through on his threat when it fails. Upon acquiring the ghostlight, Viker corrupts it and uses the "ghastlight"'s power to amass an army of malevolent ghosts, seeking to kill the living and turn the world into his dominion of the dead.
• The Woobie:
  • Rebecca Strand had to watch her father get murdered by a ghost before suffering the same fate immediately afterwards, and has spent centuries with barely any human contact. She harbors immense guilt due to feeling like she failed her father, while also resenting that she'll never get to live a full life.
  • Gabe's father left his family to be with another woman, and then shortly afterwards died in a car accident, with Gabe both missing him while also feeling like his father didn't truly care about him. In addition, he ends up being forced to watch his ghost get devoured by Viker, while being unable to stop him.
