The cast were great for the whole trilogy as well as their characters and backstories but they were completely let down by the unnecessary need to employ over-dramatic screenwriting far more befitting a stage play. I see this a common thread in David Hare's writing, it just doesn't translate well to screen performances where there could be a lot more subtlety instead of hammering home some overly emotional dilemma, which if you look at the character situation logically often makes very little sense.
