I loved it. Terrific acting....esp. of course from Helen Mirren. Don’t know how anyone could really have been taken in by “Roy”.....but some people, esp. if they’re lonely, will believe anybody.
Where this film was clever, I think, was that there were early hints of Betty’s enlightenment, which were followed by increasingly affectionate behaviour to Roy. it wasn’t until the final denouement that we realise that Betty was totally across the situation, and had been for most of the time. Her gradual tightening of the noose round Roy’s neck was masterly. It’s worth going to see this film if only for Mirren’s tour de force.
