What does it mean that family interactions are now mediated through digital technology? Phones have been around our whole lives, but now every call, every text, and every importany moment are silently archived, shared on the internet, easily searchable. It’s an interesting idea that’s not particularly explored Searching, a frustrating thriller wrapped in a maudlin family drama. (The hammy score really kills any edge that this Hallmark story might contain, and the twists are all pretty predictable.) You spend most of the movie looking at computer screens, surveillance footage, and TV news reports, but there’s no real reason for the film to do this. Stars John Cho and Debra Messing do most of their interacting via FaceTime, which might be a fun acting exercise but which gets pretty tedious after the first hour.
