I don't know why this movie got Oscar, seriously movie has incomplete story and weak story. Director didn't use the concept properly and sone parts of movie ar still mystery. Very poor direction.

Thriller part come at Last and it's also not interesting. This movie can be good if they use concept properly with proper direction. In starting face it's story is very predictable. I don't know why Oscar selector choose this movie. This movie is not eligible for nominations. I literally don't have trust on Oscar after this movie. Can't believe that it's IMDb rating is 8.6. Weak story and poor direction can't win Oscar.
