premise: Other critics say the play has outlived [its] raciness (David Patrick Stearns, USA Today ). Although La Ronde was banned at the turn of the century, nowadays its account of sexual encounters among various characters (all played by Kidman and her co-star Iain Glen) seems pretty tame.
hypothesis: La Ronde is a chaste play which is lacking in sexual encounters between its two stars, Kidman and Iain Glen.
