47 METERS DOWN is a suspense horror film about two sisters (which I didn't realize until later in the film when Lisa states that Kate is her sister) who have ventured out for a relaxing and adventurous time with each other. One sister, Lisa, is attempting to move past her broken relationship, while the other sister, Kate (also the younger sister), has been out living life and enjoying adventures. Kate talks Lisa into going out on a boat to see some sharks, which has Lisa very frightened. However, Kate is able to talk Lisa into pretty much anything, and they end up going, which costs a couple of lives, and a lot of time.
There is a lot of suspense in this movie as the audience gets to wonder continually if Kate and Lisa will survive the mishap that left them 47 meters below the surface, with only a little bit of air, and a couple of man hungry sharks. Mandy Moore does a good job as Lisa, but there were several times in the movie where I wanted her to be eaten by a shark. She screamed a lot, and whined over and over and over about being scared and not being able to do this or that because of her fear. Kate, played by Claire Holt, did a much better job, screaming when it was warranted, and I really didn't hate her character at all. While throughout I didn't care if Lisa died, I found myself hoping that Kate lived.
As someone who doesn't find much scary anymore, I will admit there were a couple of times while watching this movie that I did jump, and I was on the treadmill, which almost caused me to fall off. This of course, would have been hilarious, but I am glad I didn't fall off of the treadmill. This is me doing you a solid though, don't watch this while you are on the treadmill, or prepare yourself for some jump scares (which were well done and warranted).
Now for the bad. There is a section of the movie, towards the end, that wasn't good. It tried too hard to make this one point believable and it only served to annoy me. I don't like any of the following because they are overdone - a dream within a dream, someone hallucination that they live, someone hallucinating one thing which turns out to be the exact opposite of what happened, or someone hoping for something so much that the director decides to show us them escaping, then drags us back down into the hell they are trapped in. While this worked in the movie THE DESCENT, every other time it has been used has been overdone. So, that was the only scene in the movie that I did not like, for one it was an eye-rolling moment, and for two it didn't fit the format or theme of the movie.
