This is not "Mission Impossible: Panties in a Twist" or whatever the latest incarnation is. (And I do enjoy those!) This movie is is a character study, an abundance of beautiful cinematography, and a shark chasing thriller all in one. There is a sense of realism, especially with the interactions between the characters, who react in line with their own backstories- characters who are simultaneously heroic, anti-heroic, brilliant, and ridiculously self absorbed and stupid.
Additionally, Dark Tide perfectly captured the sense of sheer peace and quiet that consumes you once your head is below the waves in the open ocean. I've been scuba diving all over the world, and driven a boat like in this movie. The movie captured the sense of reverence in the water and for the water, and took me far away to reefs of my own past.
Is it thrilling? Absolutely- the action scenes were tense, and you felt the weight of the sharks gliding silently just inches away. Is it slower? I was never bored. I enjoyed the characters, flaws and all. In the end, if anything, I wanted more closure and final introspection. But that is the only thing I found lacking. If you remotely like the ocean and treat it as a thriller with a slower burn, you will enjoy the movie.
6 1/2 stars.
