Most often when a film is both booed and applauded, the boos come from members of the audience who donโt want their film to to conform too much to the real world. Thus when any sense of reality intrudes โ as the real-life dialogue coaching being integrated into the film itself โ they automatically hate it.
And of course when a film doesnโt hew to the conventions of Hollywood happily-ever-after, a large portion of the audience despises it straight away, too.
I suspect though I have not seen it yet that this film is too real for many in the audience, in the sense that Johansson actually approached real, unknowing men and asked them to get in her van. That and the other bits of reality incorporated into the film unsettles the weak-minded, I think. Of course it is designed to unsettle, and those elements are what might make this film great.
Canโt wait to see it.
