Keeping a foot in both worlds as Melinda is Jennifer Love Hewitt (Party of Five, Garfield), an actress who doesn't seem entirely natural; between her cartoonish physical dimension (the show isn't shy about displaying her bosom), her fake eyelashes, and the seemingly molded contours of her face, she's like a life-sized doll. Unfortunately, this quality lends a similarly plastic feel to her telegenic smile and earnest looks of compassion. The scripts are strictly middle-of-the-road tv fare, with obvious turns of plot and heavy-handed emotional crises, but the special effects conjure some eeriness. Extras include docs on the show's development, the lovely opening credits (based on the art of Maggie Taylor), and the paranormal investigators whose work inspired the show, along with a handful of episode commentaries and deleted scenes. Fans will not feel cheated. --Bret Fetzer
