I'm not completely sure what I have to say about Harvey Fierstein's Casa Valentina, except go and see. The ensemble is superb, and Joe Mantello's direction seems to hark to another vacation-home work he did at MTC, Love! Valour! Compassion!
The first act is the stronger of the two; the second-act drama goes a little abstract, asks a lot of questions it doesn't answer. And it's unsettling (by design) that the haven so carefully crafted in the first act is so easily shaken in the second.
And I've been to Casa Valentina. We don't call it that, of course, ours is Inferno. But it was interesting to hear the core of it so clearly. Differences, to be sure, but fundamentally this was a very familiar place.
