How can one describe a movie that didn't engage them?

The selected response effectively conveys a lack of interest and engagement with the movie, directly stating the viewer's experience. This straightforward expression captures the essence of a negative reaction without embellishment, indicating that the film did not stimulate any curiosity or emotional response.

The other choices, while they discuss the movie in different aspects, do not reflect a lack of engagement. For instance, stating that the movie was "fascinating and engaging" or "full of suspense" implies a positive experience, while suggesting it was a "critical success" focuses on external validation rather than the viewer's personal reaction. Thus, the choice succinctly encapsulates the sentiment of disinterest, making it the appropriate selection.
