First, this is an extremely witty script in English, but even more so in French - I'd say the wit in English is about 75% of that in French.
But, fortunately, the excellent cast of characters all have wonderful talent for expressing their roles through their facial expressions, the tone of their voices, even slap stick body language.
The storyline is classic French - the satirically humorous trials of fine French bourgeoise marriage - the insecurities of the middle age men, the insecurities of the middle age women, the disrupting spice of a young nubile mistress - and all over a fine dinner of interminable French wines and haute cuisine.
Really a very entertaining performance - for grown-ups with grown-ups appreciation of the grown-up problems of sustaining a grown-up partnership.
Tres bien! :-)
