This movie is a turkey in pretty clothes.
The actors pronounce the dialogue VERY c-a-r-e-f-u-l-l-y ... you know, like they are reading off cue cards. The real reason, I suppose, is that the producers of the film assume much of their audience will have English as a second language and, well, they had to keep things simple.
Also, the actors NEVER interrupt one another. Needless to say, this grade-school-play style of acting soon grows tiresome. Oh, and the plot is historically inaccurate, which in itself would have been forgivable had the plot been internally consistent, which, sad to say, it is not.
In short Julie Delphy is a hack.
