This genuinely chilling haunted fairytale comes from producer Guillermo del Toro and writer/director Andrés Muschietti, and is based on Mushcietti’s original short film. Two little girls are abandoned by their demented father in the forest. They are discovered years later and adopted by their uncle (Nikolaj Coster-Waldau) and his girlfriend (Jessica Chastain). The little girls have taken on the characteristics of feral beasts and are convinced they are being watched over by a force they call “Mama.” As it turns out, Mama is very real, and a decent CGI creation that is both scary and just the right touch of funny. The film works well not just because Muschietti knows how to construct a good scare, but also because he does a great job getting you to care for the little girls and the Chastain character. Chastain, looking rather gothic in this one, delivers another good performance, even though she isn’t very convincing as a bass player in a punk band. I was scared throughout much of this movie.
