I saw a production in Philadelphia earlier this summer. It's an entertaining and often funny 90-minute play. I found some of the humor a little tired and felt like the play didn't push as far as it could on certain topics; I also thought it occasionally struggled to seem more profound than it is. Don't go in expecting a realistic or fact-based depiction of the three characters. Overall, I'd say I recommend it with reservations.
"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."
