In the 90s and early 2000s, Romero attempted but failed to make horror movies for children, hoping to broaden his appeal beyond the ultra-gory. Despite a few attempts - most notably Goosebumps and (I would argue) The Girl Who Loved Tom Gordon - he was unable to make that leap.
Goosebumps understandably has received the most coverage as far as aborted Romero projects for children goes, and indeed, with its critiques of capitalism and living dead threat, it's easy to see why. However, I want to talk about Moonshadows, a fantasy horror script he wrote multiple drafts for, and unlike Goosebumps, it's an original story, not an adaptation of someone else's book.
