Eh, the ages of the actors really doesn't bother me. Yes, ideally it would be nice to see a production where there are younger people in the lead roles, but it's Shakespeare- it's not like this will be the first or last time the ages in any of his plays has been strictly followed. And who knows, they could be great and the production could be wonderful. And if not, there will probably another production in NYC within five years, if not sooner.
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.
