This isn’t your typical action film; it functions better as a thriller. The narrative centers on a Marine awaiting rescue from a perilous circumstance. It’s important to understand the genre distinction because this isn't an action-heavy movie, but rather one built around suspense. I would give this film a rating of 7 out of 10. However, I do think there's something noticeable about its structure. The film seems to divide into three distinct segments: it begins strongly, then experiences a fairly lengthy and dull stretch—roughly 25 to 30 minutes—before improving considerably. The core story is well-executed, the performers are excellent, and the music is quite pleasing throughout. Ultimately, I was moved to tears; it's definitely something you should see. (7 stars out of 10)
