Didn't see the first one, but this movie was truly horrible. The cinematographer was clearly calling the shots here (no pun intended), and while some of the camera work is interesting, its way overdone.
There is no acting...
The plot is (spoiler alert) "Sharks want to eat them"...
The dialog reminds me of early Schwarzenegger flicks...
The jump scares are obvious...
Don't watch this... unless someone is paying you.
