Don't Be Afraid of the Dark never gets its stuff together. The characters are gloomy and so is the atmosphere. You never get a good enough feel for any of the characters in the film to have real concern for them.
It's a tough thing to accurately gauge how well a movie would have done if not for an unforeseen variable, such as in this case a massive hurricane that threatened much of the East Coast of the country and shut down hundreds of movie theaters over the weekend.
Based on a 1973 TV movie of the same name, Don't Be Afraid of the Dark is a horror movie that rarely insults your intelligence. Indeed, it seduces you into thinking you can outsmart the film -- and then zaps you when you least expect it. Now that's fun.
