What new classics have we declared off-limits?
Pan's Labyrinth (2006)
Why someone would want to remake it: Because it's got monsters and it's got Guillermo Del Toro's name on it and because someone with only a superficial knowledge of it probably imagines a standard horror ride. It's a recognizable title, but because it's in Spanish, there are many audiences that still have not seen it. That combination could be irresistible to someone who could cash in on it with something cheap and quick.
Why they shouldn't: Because it's not a monster movie. It's a gorgeous broken-hearted fable about fascism and power. It is innately Spanish, and telling the story in English or moving it out of the specific time and place where it's set just wouldn't work. You'd gut the thing and it wouldn't end up making any sense. The film is a dream, a dark and personal fairy tale, and without subtext, these images mean nothing.
