Despite admiring the realistic and understated tone of the narrative, even at a mere 90 minutes, this film feels padded out in plot and boring because it keeps reiterating its story elements. The ending may have a good emotional punch, but that's because the entire movie is only about the buildup to an obvious downbeat final note. And, dare I say that it's not very tragic because the victim's not sympathetic.
This film is the sociopathic sister of "Pan's Labyrinth". All the inocence, everything that was pure in Del Toro's film is absent in this haunting story about a little girl that convinces another one that she herself is an evil old witch. This is a magical film, but it certainly is dark magic.
Taboada succeeds in unearthing the menace that lurks just beneath childhood comfort, that feeling of uncertainty and terror the world can evoke, and the subtle cruelty and manipulation children exert over one another.

When my brother asked me to describe this, I came up with Pan's Labrynth meets Leave her to Heaven. I think that description holds up. I fell in love with this film, even before it was over. I was captured by the incredible and playful cinematography. The story itself is very good, and the performances are even better. I think it resembles the type of films I would like to make one day.
