Quite twisty and with some nicely fitting together plotting and foreshadowing around the mystery of what happened to 16 year old Margot Kim (although I could tell the film wasn't going to go too dark, which made some of the possibilities it raised fairly easy to discount). The telling of the whole story through screens of various kinds (mostly internet-based) worked well. Neat that the main cast was Asian without a big thing being made out of it too.
