The last third of this season was atrocious. And that was directly due to how the Elisabeth Grangier character was portrayed. There was absolutely NO arc to that character. She's a wounded duck at the beginning of the series and she's a wounded duck at the end.
This character intransigence has a devastatingly negative effect on the entire story. Elisabeth Grangier essentially has two modes: crying mode and sex mode. Whenever the going gets tough, Elisabeth Grangier has sex. Then it's back to crying mode.
Because Elisabeth is the central character, her mental stagnation results in the final third of the plot bogging down terribly. Elisabeth is constantly arriving too late, drawing conclusions that no longer matter and failing to see what's right in front of her eyes. In most movies or series like this, the mouse becomes angry and roars. NOT in this series.
The last two episodes are filled with lengthy dialogues that go nowhere. It was frustrating to watch, considering how smoothly the first four episodes played out. I fast-forwarded through most of the last two episodes. And I kept hoping Elisabeth was gonna kick it up a notch but that never happened.
It's really a shame because during the first four episodes this series displayed real potential. But for some reason the writers were unwilling to allow Elisabeth to grow into a tough-minded, take no prisoners woman. This series would have been SO much better if the writers hadn't stunted Elisabeth's growth.
