I am a huge fan of "shark" movies and honestly in the last 5 years or so there was surprisingly many good movies with this theme. My top is definitely "Shallow" and very good one was "47 Meters Down".
This one has many flaws in very basic aspects in this genre.
What do you need? You need good CGi, you need good acting and most importantly you need great directing so it would feel realistic.
1. CGi is 50/50 , you have real sharks (or at least it looks like it) but the problem is it looks like a documentary movie, which is not a good sign. And then you have bad very unrealistic scenes with shark. So most of the time it doesn't fit the movie
2. Memorable scenes, you will not find a single one. And that is bad. You will see 10x the same scene with a fin on the surface, you will see lots of bubbles and splashes and you will see few times something under the surface (should be shark) that looks like someone draw it with a marker.
3. Victims and story. Sometimes filmmakers have tendency to forget what genre they are filming. This seems that case. This really feels like a drama with her personal trauma set in the water where by a chance is THE shark. It should be other way around. Another thing is, don't try to force some pathetic story to "catastrophic" movie. There is no need. This should be about surviving, not about trying to overcome your fears of diving. On top of that when you lost someone, it is more than obvious they will not make a movie you will loose someone else. So after 10 min you know who will survive and who will not.
It's not hard to have a right vision for this kind of movies, but why filmmakers are trying to do something "more" is beyond me?!
Overall this is slightly below average movie. There is really no need to watch this because you will be disappointed and after 40mins you will check how many more minutes it will take to end this "journey"
