If you liked Pan's Laberinth and The Devil's Spine, then Guillermo del Toro's latest, The Orphanage, will surpass your expectations. As with PL, it is a tale of childhood lost, and as with TDS, it is a ghost story. If you are familiar with the current wave of Thai-Horror, then you should be surprisingly pleased with TO, which coalesces horror with sentimentality: fears and tears. Worth a second and third view.

P.S. I saw it at an Art Theater in limited release, and I don't know if it will gain wide release. Best to catch it now.
