Lights up on a chintzy-looking car and a wall made out of black suitcases: consider this re-enforcement of the positives and negatives of Kate McGovern's new play, Blue Before Morning. Over the next ninety minutes, a lot of things are squeezed into that car and rather showily discussed, but very little actually opens up, and that wall of baggage never comes down. In truth, the play is a little well-planned for a spontaneous road trip, one caused when the young Ava (Kether Donohue) hails a cab driven by the amiable Jerry (Chris McKenney), and manages to guilt him into driving her from New York City to South Carolina. Along the way, he picks up a third-trimester hitcher, Ella (Jenny Maguire), as he can't stand to see her get soaked. While Gia Forakis's neatly choreographed segues work (accelerated video shows the passage of time), McGovern's short scenes ("Doughnuts," "Obstacles," "Birthdays,") come across as overplanned. Credit the writing that it remains enjoyable up until the end: it's a shame the luggage is missing.
