Kahless’s review published on Letterboxd :
An intimate play, taking place almost only in the apartment of one couple (Foster, O'Reilly)... Carried by the great performances of all the four actors. It is really hard to say which one is the best, Waltz has some of the best lines, however Foster, Winslet and O'Reilly are en par too. Great movie, hilarious at times, however the deeper meaning never goes out of focus. Recommended!
