Their conversation is interesting enough, even the glib, rather cliched posturing about art and artists.
Some is serious - artists are "at the mercy of someone else's tastes" - and some is amusing - "We like art ... we both love the Impressionists," says Sadie to the "conceptual" artist (Simon London).
Australian playwright Joanna Murray-Smith, a chronicler of the affluent middle-class (Honour, Female of the Species), writes dialogue with good rhythm, occasional witticisms and a fondness for aphorisms.
However, the play prefers telling to showing, and if subtle social commentary or irony lurks behind the dinner party pleasantries (not a given), it falls flat.
Once the younger couple have made their outrageous demand, the set-up would be better served by broad comedy and satire, for which it's easier to suspend disbelief.
The characters are all relatively straight roles played competently and professionally; no scenery-chewing or flamboyance here.
Instead of changing their clothes to show the passing of a year, the actors simply throw on blazers over their old duds.
The chunky turquoise abstract-yacht set feels luxurious but rather anonymous, and banks of screens show mawkish images at the end.
Diverting if baffling.
