It is a deliberately provocative and hugely upsetting movie and the two actors brilliantly depict the dysfunctional grieving couple with nothing left to lose.
The whole thing pretty much unbearable to watch in the company of the two people who brought you to this world, however, the sickest scene of the movie happens when Charlotte’s sexual sadism surfaces at its finest.
It is perhaps best to see it for yourself, but male-readers, be warned, it is not pretty.
