Like a Beckett rewrite of Witness for the Prosecution - great buildup and then Godot never shows.
I'm seeing lots of extreme reviews of this, people saying it's the best film of the year, and people saying it's a snoozefest. I think the truth is, as usual, somewhere in the middle. There's a real intrigue about the characterisation and the plot. I went in knowing nothing about the film and because of that, and the way in which it drips information to you, was always left wondering which way it might turn to give a payoff for its build-up. The issue is that it doesn't. It creates intrigue and human drama for over 2 hours, with titbits of unreliable narration and hints at sinister machinations. And then it just sort of ends.
