Started off very well: Nicole Kidman in typical ice-queen mode, Liev Schrieber playing the dusky husky philandering husband, and Dakota Fanning and others nicely setting up a Dallas-style spoilt rich brat vibe for lots of outrageous shenanigans up in Nantucket. But quickly you realise there are no sympathetic characters: you wish someone would bludgeon the lot of them to death, and rather than letting the characters do their thing, the narrative is very plot focussed, and the plot6 is just not remotely plausible. There are the typical gumshoe tropes of *everyone* having a motive and OF COURSE it is the person you least expect (okay we had picked the Polish maid as an outlier but we weren't that far off.
Ultimately felt like time I'll never get back.
