Theatermania has the first professional review of this I've seen, which is pretty mixed:
In her debut as a musical-theater songwriter, Saliers proves she can write a catchy tune. Still, the 20 or so original songs in the show sometimes blend together in a manner that leaves you feeling like they could be assigned to any character—or perhaps recorded by Saliers and her partner Amy Ray for the next Indigo Girls records. Surprisingly, the song that works seamlessly from a narrative standpoint is a jukebox addition: the popular “Closer to Fine,” which opens the second act. It captures Cyd’s inner turmoil and desire for love in three concise minutes. The rest of the show is frequently close to fine, but not better.

"You travel alone because other people are only there to remind you how much that hook hurts that we all bit down on. Wait for that one day we can bite free and get back out there in space where we belong, sail back over water, over skies, into space, the hook finally out of our mouths and we wander back out there in space spawning to other planets never to return hurrah to earth and we'll look back and can't even see these lives here anymore. Only the taste of blood to remind us we ever existed. The earth is small. We're gone. We're dead. We're safe."
