This film clearly considers itself to be very clever (& classy). It is at least fairly well mannered. Clever? No. A decent episode of Columbo or Poirot(Suchet) is far more satisfying. I was glad when it finished. There's no depth to this. Kermode thinks it's a work of genius. It isn't. Was Daniel Craig impressive? No, not really. Was anything else impressive? Not at all. A decent cast which delivers almost nothing. A work of no obvious merit that's totally overblown.
