I was confounded. I thought this daring opera take on the Michael Cunningham book and the 2002 film starring Meryl Streep, Julianne Moore and Nicole Kidman would be a tedious rehash. A trilogy of women in different times linked only by Virginia Woolf’s novel, Mrs Dallaway, heading towards, or encountering suicide, only a sing-along this time, did not bode well for an engaging evening. What could the medium of opera add to the deeply troubling film?  Plenty, as it turned out.
