JK Rowling - does she read reviews?

I just wonder how J K Rowling is feeling today? She appears to me to alternate between robust and fragile. Does the mega- global success of Harry Potter make her immune to critical reviews? What's your take on her latest work and its reception in the media? This from the Sunday Times 'Her book's concluding avalanche of calamities and corpses would cause even Thomas  Hardy to blink.' Paul Kemp. And Minette Marrin, also in the SundayTimes 'Casual vacancy for gloomy snob: would suit Jk Rowling.' Ouch!
