Rob Lowe and his sons have joined the legions of ghost hunters that populate cable with the new show "The Lowe Files." It's a goofy bit of Scooby-Doo-like hijinks for the A&E network. The odd series introduces Lowe, who promptly rattles off a list of his credits, and his college-age kids John and Matthew. The series is narrated and produced by Lowe. The concept is basically for the trio to explore the paranormal and other "unsolved mysteries" together.
