I mean, it's nice that the queen is an old lady, and I respect all old ladies just for being old and surviving to their 80s, and having nice manners (as the queen seems to).
And it's nice that William and Catherine got married last year. But then, lots of other people also got married last year. And some of them also wore nice frocks (not William, of course).
So why else do people 'love' them?
