Roger Ebert calls it "a superior ghost story" while Claudia Puig calls it "a terrifying horror thriller well worth seeing." The Orphanage (El Orfanato), in Spanish with English subtitles, is not really that terrifying, but it is worth seeing. It has all the trappings of a ghost story: the creepy old house in the middle of nowhere, a lovely little child with an uncertain future, a mom who loves him, and old crones that wander in and out of the story.
It's not scary, scary like the Exorcist, and it's not really violent and funny like Severance (how I love that movie!), but it is, as Ebert says, a superior ghost story and I really enjoyed it. Rated R for some disturbing content. For more reviews on this and other films, check out the Movie Review Query Engine.
