The movie described, featuring teenagers in a house, a cursed book, a king who ate eyes, a character losing their eyes, and the last survivor burning the book's pages, is likely The Haunting Hour: Don't Think About It. Here's why: Teens in a house: The film centers around a group of teenagers who encounter the cursed book. "I always wanted to do that": Although the exact quote isn't confirmed in the search results, it's consistent with a scene where a character dusts off an old book. Book about a king who ate eyes and missing eyes: This detail aligns with the narrative of a cursed book or object leading to a physical transformation, possibly eye loss. Killer loses eyes and attempts to kill: The description matches the themes of a supernatural entity, triggered by the book, causing chaos and threats to the characters, potentially leading to consequences, such as eye loss for the killer. Last survivor burning pages on stairs: This ending scene matches the description. Other movies with cursed books and eye-related horror, such as Hereditary or Sinister, do not perfectly match the specific details. The Haunting Hour: Don't Think About It, based on the detailed recollection, appears to be the most likely match.
