Samuel D. Hunter creates worlds of complexity and heartbreak in the most banal settings. A Bright New Boise, which premiered in 2010 at The Wild Project and is now making its off-Broadway debut at Signature Theatre as part of Hunter’s Premiere Residency, takes place in the windowless break room of a Hobby Lobby in Boise, Idaho. Under Oliver Butler’s skillful direction, with a strong ensemble and remarkable lead performance by Peter Mark Kendall, Hunter’s characters engage in a desperate search for meaning in ways funny, painful, and devastating.
