John Gun’s review published on Letterboxd :
Dreadful film. I'm no fan of Thatcher but there's an interesting story to be had from her life but this pantomime of a film fails to find it. The totally fabricated scenes of her talking to her dead husband as she goes quietly insane were awful. And while Steep was occasionally brilliant, she appeared to be channelling Jennifer Saunders for most of the film. Avoid.
