Playwright Gordon Dahlquist’s [Veil Widow Conspiracy] wields those unnecessary, pretentious brackets as a warning, perhaps, that there’s a lot of extraneous information in his overstuffed 75-minute play. Set in three locations, the National Asian American Theatre Company production opens on a couple who are seemingly sheltering from some dire events outside, primarily conveyed through sirens. It’s an apocalyptic Brooklyn, but too briefly and sketchily presented to capture one’s interest.
