I rarely watch movies, and have seen Meryl Streep only once recently, in The Devil Wears Prada (don't ask me why I saw this movie!). I thought Streep was obnoxious in that movie, but since that was the role she was supposed to play, she must be a good actress. All good. No issues with that. (On googling I've also found that I've seen her in Kramer vs Kramer, decades ago.)
As far as the Margaret Thatcher movie is concerned, I have no intention of watching it since I'm not into biography (I'd rather watch Imax wildlife or space movies, or James Bond movies). I am also aware that Streep disagrees strongly with Thatcher (e.g. "I’ve never been thrilled by her brand of politics"; "I still disagree with many, many, many of the politics, but she turns out maybe to have been right about one or two things").
Regardless, I have been comfortable with Streep acting as Thatcher. An actor is a professional, and doesn't have to agree with the views of the person being represented.
I'm afraid, however, that after reading about her acceptance speech at the Golden Globe awards ceremony, I'm no longer "neutral" about her. She may still be a good actress, but she is not a good person. She seems to have allowed her hatred of Thatcher to influence the way she has portrayed Thatcher's character.
This is what she said yesterday:
'I gotta thank everybody in England that let me come and trample over their history.'And talking about her role at a press conference afterwards, Meryl admitted she did not have a positive view of Lady Thatcher. 'I think coming into this I had a very reductive view of Margaret Thatcher, so I sort of did what we all do to political figures we don’t agree with — we turn them into something more than human and less than human at the same time.

This approach indicates mischievous intent. It is unethical to deliberately paint Thatcher incorrectly, so as to fit her preconceived (and seriously ill-informed) notions.
I now agree with Steve Kates that the Margaret Thatcher in this movie is a "third rate version offered by Meryl Streep and our socialist film industry". I believe Streep has betrayed Thatcher.
Along with Steve Kates, I recommend that those interested (not me!) should watch the real Thatcher, instead. No FAKERY and FRAUD involved in the REAL Thatcher, below:
