The reason why the ending was considered sloppy was mainly because the film was rushed at the end and did not give the audience enough time to understand and digest the plot. At the climax of the movie, the main characters were locked in the car and faced a life-and-death crisis. However, the movie did not give a clear ending. Instead, it suddenly switched to another scene, making it difficult for the audience to understand the fate of the main characters. This approach made the audience feel that the ending of the movie was sloppy and lacked logic and depth. At the end of the movie, there were some abrupt twists, such as when the protagonists were released and found that the other party did not give up on hunting them down but continued to search for them. This kind of twist seemed to have no foundation and brought confusion and dissatisfaction to the audience. To sum up, the sloppy ending of the movie was mainly due to the haste and lack of depth in the plot. However, this was also a style of the director, Nolan. He often used complicated twists and unexpected endings at the end of the film, which often won the audience's love and praise.
