The ending was a good twist.

Stellar acting. Grizzly but engrossing plotting with twists.

Excellent performance by Carey Mulligan with a strong screenplay! The supporting cast was also very good. It felt a little long; the "chapter" markings were interesting but I don't think they were needed except the last one which was very clever.

It wasn't as dangerous as the premise set it up to be but it brings up a lot of good issues. Great cast.
