Rosenbaum likes it
I didn't really liked this film, but Jonathan Rosenbaum gave it a thumbs up, and he probably knows better than me.

Some would say this film is made for the international festival audience, and that is why it didn't work in Chile. I don't know.
Edit: Rosenbaum's top 25 of 2005 in "Slate":
"Play. A first feature from Chile by Alicia Scherson, packed with ideas and pirouettes, that gave me enormous amounts of pleasure both times I saw it. It showed at both the Tribeca and Chicago film festivals, won a prize at the former, and is still making the festival rounds. Since it's dated 2005, it may reach us on DVD in 2006 or 2007."
