Completely agree with this.
Very happy for her and her family that she has finished her chemotherapy and is feeling strong enough to resume a few duties and obviously have sympathy with her words but whichever PR guru directed and advised them on that film ought to be sacked. The wheat fields and the filtered light
strikes the wrong tone imho. And agree it was too long.
I think it would have been better if she had been filmed on a semi-official, semi-casual visit to a cancer charity, sitting in on a group therapy session or chatting with hospital volunteers with a simplified message played over the top.
