The film has a faster pace at the beginning and slows down as the plot progresses.
We are introduced to Cem, a Marine who has no flair for romance and with Alara, an archaeologist who is reluctant to get involved with Cem because her work as a soldier offers many risks, and she wants something stable, something he cannot offer.
The plot unfolds simply, with the couple's difficulties and how they deal with them and the veiled promise to go to the Blue Cave.
When we reach the end, in the final plot, the viewer is surprised by the twist in the plot, perhaps if the film had more time on the unfolding of some actions or more screen time for the main couple. The end of the film would have more impact, an extra 10 minutes would have been enough in my opinion.
Finally, it is a good film for those who like the style of romance, adventure, the plot is not deep and does not ask you to dwell on it, but it asks you to understand the motivations of the main couple and try see through their eyes.
