While I have the same dislike for Chucky as you do, I think he has improved his image among Britons. He has somewhere around a 50% approval rating and a low “dislike” rating.
He won’t be loved like the Queen, but unless he is a complete bork, he won’t be disliked for the short time he reigns.
Why does everyone keep saying Charles’ reign will be short? It could easily be 20 years. He’s got good genes.
