Why is the polygraph dubbed?

The film producer didn't explain why he dubbed the film Lie Detector.

It is really a serious injury that "Lie detector" is dubbed instead of Mary's original sound. Mary's northeast accent is too familiar to the audience, and it sounds awkward, not to mention that many places are not right.

In the voice, Mary is actually no longer the happy Mary and the picky Mary. That's why "Lie Detector" is obviously a comedy romance starring Mary and the article, but it didn't attract the audience who liked Mary's performance, because it really lost Mary's characteristics.

The ending is inexplicable

To sum up, one of the biggest problems of this "polygraph" is not only that it has not reversed the ending, but also that it has not adhered to the main line.

Therefore, this "lie detector" has been vomited by countless people both in the cinema and on the webcast platform, and has been scored low by countless people. There's nothing wrong with it.

Mary, the star of this film, is actually responsible. After all, she dared to accept such a puzzling script, really because she didn't choose the script carefully.
