Short version: There was a Swedish interviewer once who had a gag where she asked her interviewees to jump (a perfectly harmless gag, mind you). When the interviewer had Margaret Thatcher on, Thatcher downright refused to jump on cue. Cheerfully. Without apology. The word ‘puerile’ was used. As Maggie put it:
I made great leaps forward, not little jumps in studios.
Claire Berlinski has it right, I think: it doesn’t quite ring true for Maggie Thatcher. The family’s also reportedly not happy about the script. So, my remaining hopes on it not sucking are now reduced to:
Early trailers often make a movie that doesn’t suck look like it sucks.
Meryl Streep has sufficient professional pride (and enough of a healthy desire to not wreck her largely apolitical professional reputation) to not do a hack job.
Neither hope is precisely forlorn, but it doesn’t look good.
