What is a suitable way to say that a movie did not capture your interest?

The choice that states, "The movie failed to interest me," effectively communicates the idea that the film did not capture your attention. This phrasing directly expresses a lack of interest, emphasizing the personal reaction to the movie. It clearly conveys the sentiment without ambiguity, making it evident that the movie did not meet your expectations for engagement.

In contrast, the other choices suggest various levels of interest or success that do not align with the intent of expressing disinterest. For instance, noting that the movie was entertaining implies a positive experience, while stating it was a box office hit suggests popularity but does not necessarily reflect your personal feelings about it. Similarly, describing a movie as engaging to the audience may reflect the views of others but does not indicate your own lack of interest. Therefore, the response that explicitly addresses personal disinterest is the most appropriate for conveying the intended sentiment.
