The play is beautiful, wrapped in an innocence characteristic of Lorca's - but to an audience not used to dealing with parables and metaphors, it might look like a story for children. Far from it.
So I take my hat off to Hip Pocket Theatre in the USA, for staging what looks, from the reviews, to be a very succesful production. (I am a little bit jealous that I didn't have the guts....)
Good luck with it from the other side of the pond.
(I would have liked to post this earlier to raise a bit of awareness but haven't been able to.)
