Mimi is destined to be reduced to the form of a 'fantasy' when she decided to ‘leave the words to Oscar’. Her own power over every related interpretation is thus given away, and herself, at the mercy of the opposite sex, regardless of which man in particular.
That's why I almost considered it fabulous ly and ironically triumphant at the scene where Mimi and Fiona joined a dance free from any description from men. They were literally celebrating that the fear of getting hurt was gone for the moment.
But, again, why I found this film extra outstanding, the true end remains disgusting after all as the two men joined to make a comment over the unconscious and wordless women. They're once more put in the position of inability where they belonged before, and for ever more since nothing had changed. Even the decision of death was made by Oscar, who also drew a seemingly feasible conclusion('too greedy'). It doesn't even stand to suffice to close this story. Same old stuff. In this sense, Polanski put up a mirror in front of us which reflects the frustrating reality and that only.
When Fiona and Nigel embraced each other at the end of the film, they seemed as if to fall apart any minute. It makes so much sense in that it's all built upon a lie that they were still in love. They got stuck in the inertia of what used to be love.
The very last thing, the actor for Oscar should have the last name of Coyote. It suits him no better.
