This teen-oriented thriller warns against the dangers of blind conformity, which would be more credible if it didn’t open with a string of product placements (Google, Spotify, Huffington Post). A responsible high school senior (Emma Roberts) joins an online gaming community called Nerve to test her mettle; its anonymous “watchers” pair her up with a stranger (Dave Franco) and dare them to execute increasingly dangerous stunts for cash. The story is intriguing, and the heroine’s backstory is developed enough to explain her suddenly reckless behavior. But the film has a fatal messaging problem: it lambasts online group-think and “hiding behind screen names” while also glamorizing the game. By winning, the teens get everything they want and more. Henry Joost and Ariel Schulman directed; with Juliette Lewis, Emily Meade, and, from Orange Is the New Black, Samira Wiley and Kimiko Glenn.
