Where to start with this:
acting all round, especially Olivia Colman, though I feel bit unfair ranking her when Emma Stone, Rachel Weisz and Nicholas Hoult were so entrancing too.
Outstanding costumes and tip-top disco dancing (spoiler alert).
It's petty much plot-free on the obvious level, though based on historical events and real people. Replete with anachronistic language, but deliberately so, so trés post-modern.
I loved it.
