Marketing can make or break a movie, and “Crimson Peak,” Guillermo del Toro’s newest film, is in serious danger. The previews and pretty much every other bit of marketing make it out to be a horror movie, but it’s a classic Gothic romance. Like “Rebecca” and “Jane Eyre,” it brings us a heroine who is drawn by love into the web of a strange and horrifying mystery. People expecting a standard gory, violent modern horror flick are likely to be disappointed, but folks who adore creepy atmosphere, gorgeous and decaying upper-class dwellings, and Tom Hiddleston are in for a treat.
