I enjoyed this movie more than I thought I would. After reading some of the reviews I nearly gave it a miss, but being a big fan of shark movies I decided to give it a chance. Despite the cover leading you to think the sharks are a fanciful size, the actual shark footage was believable and thankfully not overdone.
This is a standalone movie but I would put it on a par with the first Open Water movie and I liked it much more than the ridiculous Open Water 2. The acting was good and while some parts dragged on there was enough (including a few jump scares) to keep you invested in the story.
Some reviews have compared this with "The Shallows" and while this movie is different in many ways it was refreshing that the sharks weren't single-minded in their efforts to get their prey. This movie doesn't pretend to be a masterpiece but certainly has some good moments and is worth a viewing.
The very low and very high reviews are hard to take seriously and despite some of the more annoying moments I reckon it's a solid 6 out of 10.
