I actually find it odd how vitriolic posters get towards Kate. She doesn’t have any of the qualities normally associated with a ‘love them or hate them’ personality.
She looks like she makes an effort to get the role right - she’s happy and smiley or somber and empathetic at the appropriate times.
She seems to have good relationships with the majority of her family and married family. She has loyal friends.
In over 25 years in the public eye there have been no scandals, no serious missteps, or controversies.
I would assume that at worst you’d be bored or indifferent to her.
