I have no real criticism about the actors (though the husband sounded more Antipodean than British to me), but - what was it about? The plot made absolutely no sense! It hurts that I sat through it to find out that the plot couldn't be and wouldn't be decipherable to a semi-sane adult. Avoid. Like. The. Plague.
