This is the gripping “found movie” for a perpetually plugged-in world. In Aneesh Chaganty’s Searching (B+), the protagonist father portrayed wonderfully by John Cho often contemplates sessions further down the web’s wormhole while resisting the notion to simply shut down. Grounding this mystery thriller, Cho’s desktop pop ups the ante – online, engaged and amplified – and embarks on an emotional arch of triumphant connection over isolation. The propulsive plot about the disappearance of his daughter grants viewers a tense window into his soul and mindset, while the film’s action takes place largely in the virtual environment of computer and surveillance screens. It’s the Who Framed Roger Rabbit of social media tropes: humans mixing with fetching FaceTimes, charming chatbots, brilliant browsers and suspenseful streams. Among the emojified denizens and avatars, you almost suspect a cameo from an animated paperclip! Chaganty’s inventive high-tech hub is ideal for clue reveals stashed in the cache: flashbacks by archived selfie confessionals, public actions by viral video and forensic breadcrumbs dotting the underbelly of the social graph. The realistic interfaces are sturdy supporting performers, as is Debra Messing playing nicely against type as a hard-driving detective. While the film’s procedural formula doesn’t always measure up to its creative format, the #SearchingMovie is well worth discovery.
