An hour into The Best We Could, you realize you’re not watching the play you thought you were. Emily Feldman’s new drama seemed like it was a semi-experimental staging of a cross-country drive during which a grown woman and her dad visit national parks and revisit moments in their lives. Then, all of a sudden, it’s about something very specific beyond the sightseeing, bonding and memories. And the play belongs to a particular category of stories—and that category is not road trips or family relationships or Our Town riffs.
