Hydrangeas: Serrata hydrangea has a problem, 0 by showmestate

This is "Miranda" a serrata hydrangea. I'm guessing it's either getting too much water or too much sun. The water is partly my fault and partly mother nature. We've had about three straight days of rain. And I was watering quite a bit before that. It was looking perfectly healthy before all this rain started.

Can anyone tell what is wrong with it? We've had so little sun lately, I didn't think it could be too much sun. Will it recover - can I do anything to help it?
