Most of the criticism of this production seems to center on the lack of subtlety of the actresses. Were the production a film or television show, I might be inclined to agree, but this was a stage production and meant to be seen by an audience some fifty or more feet away.
I thought the performance good, though its script is dated in its outlook on women and their reliance upon men. The characters are stereotypes and obviously were written to be just that way. The actresses play them with gusto, and the audience's reaction indicates that the performances went over well in that theater - although I agree that Tilly's brassy and nasal portrayal of the 'other woman' left me wondering why any man would be interested in her Crystal for anything more than a quick fling.
The close-up camera work for this video production doesn't do the show justice as the actresses are not playing for a camera, and the video audience therefore sees only the "over-the-top" look of these women projecting for a theater audience.
