Hollywoods exploitation of Margaret Thatcher?

This article in the Daily Mail has a lot of interesting comments by a lot of people who knew Margaret Thatcher personally. I suspect that these articles are as interesting as the new movie about her is. One typical comment is given by Eve Pollard:

this invasion of the privacy of an 86-year-old-widow is truly shocking.
It reveals the most powerful woman the West has ever known as frail, feeble and lonely. But, you feel, almost against their will, director Phyllida Lloyd and screenwriter Abi Morgan (neither of whom, I suspect, would have approved of Mrs T when she was in office) couldn’t help but make an ill and powerless Margaret Thatcher sympathetic. . . .
