There was a good film in there, but, instead of closing in like good cinema noir, knightley's paranoia goes from zero to 100 before you can say rear window.
There doesn't seem to be much of an act two in which to explore, dislike and guess about the rest of the cast. And then...........
We're asked to believe that a 5ft 5 angle poise lamp can jump into a fjord, swim to shore, ramble her fjord soaked way until she finds a Hunter's unlocked cabin, start a fire, find dry clothes that fit, walk to a gala dinner venue, sneak in, persuade security that she's kosher and reveal the baddie on stage in front of the guests.
Really!!!! Really!!! Even Magnum PI would struggle.
Act three is only on nodding terms with one and two.
And just to keep the wokeratti onside, towards the end a man tells the female intern to make him a cup of tea with two sugars (Sweeny style) and she ignores him, good lass.
Should have been good, but what a dog's dinner of a film. This is what happens when you let children with only 4 colours on their pallette write scripts. Somebody make it stop.
