Haven't seen the film.
As an English woman, for what it's worth, I think the P o W, his lover and his wife were every bit as bad as each other.
I loathed the prurience of the press and the public, loathed the manipulated 'out-pouring of grief' that was the funeral, thought her brother was misguided in his eulogy (some things are best left for private), I really can't understand and can't stand the Cult of Diana at all. And whatever you read in the press, I'm really not the only one.
The best thing the House of Saxe-Coburg-Gotha could do would be to keep themselves to themselves. Especially Di's kids.
I have the greatest respect for the Queen who I believe to be woman of faith, integrity, and commitment, although I'll never be buying a commemorative plate
