Very very excited for Natasha, Pierre, and the Great Comet of 1812. I'm also intrigued by The Front Page, which is a play I don't know but thus far the announced cast is pretty great. And I'll be curious to see Stephen Karam's adaptation of The Cherry Orchard as well.
I am a firm believer in serendipity- all the random pieces coming together in one wonderful moment, when suddenly you see what their purpose was all along.
