The twist is actually a real twist not some lame remake twist, but a real twist that is actually scary like the Uninvited even though the movie was a remake. They made the story a little more original.
overall, I'd have to say that this movie is one of the best scary movies this year besides the foreign straight to DVD films. It is a huge improvement for the director over the House of Wax. We finally have a creepy kid movie that doesn't involve demonic possession or exorcism.
