After watching the trailer of the film, I think that this film should be able to enter my top ten of the year. Perhaps the expectations are too high. After watching it, I do not rate it high. Clockwork said that the director is also Agatha's iron fan, so my score is still low. Agatha is one of my favorite reasoning novelists, and one is a ghost horse star. In fact, the first half of the film was completely Agatha's tone, and I was very excited to watch it, as if the scene of the novel was reproduced, but then it became tasteful. I think a good reasoning movie should be logically impeccable or the plot is pushed very fast, so you do n't have to worry about its rationality. And the most important thing to reason about the movie is the ending. If the whole movie is OK, the ending is a bright spot, it will also improve the score a lot, just like "Tuner". This movie does not have these points. If you shoot in Agatha 's style, one should be that the old man has a friend. In the letter to the friend, he mentioned that he suspected that someone wanted to murder him, so he wanted to test it. On his birthday, he put everyone Enraged because he is a writer of reasoning novels, leaving clues when he dies. Another thing is that all things are arranged by the old man, so that his children will be touched during this reasoning process and change them through death. In the movie watching, I always thought it was the latter, because the old man angered everyone in his birthday feast, and then explained to everyone that you will understand. According to the movie, it doesn't make sense. If the end of the movie is processed as everything planned by the female lead, it will add a lot of points.
