Heartbreaking and superb. Tense, witty, gripping, with genuine horror coming not from prosthetics but the bleakness of humanity. And, as you say, every step has been like a Greek tragedy - except in this one Medea is given the grace to choose another path for herself, if not for the others.

Wonderful performances too. OK, so there are plot holes I may think about later, but this was raw, powerful, deeply moving human drama about what it is to be a person.

I shall miss it. I shall miss Mitchell. But the end was right; there was no cop-out.
