Put down that phone and go watch this

Teenagers Vee (Emma Roberts, daughter of Eric) and Ian (Dave Franco, brother of James) find themselves caught up in the (possibly illegal) title app, a kind of “Truth or Dare” in which smartphone users elect to be “watchers” and pay a fee, or “Players” and get paid for completing dumb dares online. This is not great cinema; it could have gone way darker on the perils of instant fame through social media. But it’s unpredictable, moves along briskly, and never forgets that it’s telling a story. Call it a crayon-colored thriller for the wired teens of today. I had much more fun than I intended. (96 min)
