It's a solid -- if somewhat formulaic -- play that benefits from great actors and maybe the best director of naturalistic drama working today. Moretz is superb, as is the child actor. Landecker has a rather one-note role, but she does her best to add layers that aren't there in the writing. I could see this having a life in regional theaters like Steppenwolf, et al.
"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."
-John Guare, Landscape of the Body
