Eh...I wish I shared your enthusiasm towards the show. I wanted to love it, given that there were several moments that really showed the old-time Terrence McNally brilliance that has been missing from almost all of his recent work, but something about it just didn't work for me. Every time I started to care about a character, they were relegated to the sidelines so that a new character could be introduced. By the end of the play, there were too many characters to keep track of, and only about three or four of them were very interesting.
I will say that everyone in the ensemble is superb, and what McNally is conjecturing--asking (from a gay perspective) if gay marriage really is a good idea after all, rather than blind faith in the institution of marriage--is a thought-provoking new spin on the argument. I just don't think it's there yet.
"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."
