The CGI in this movie makes the Sharknado movies look pretty decent in comparison. I recommend watching this movie just to laugh at the comically bad CGI. It is so bad that it becomes pretty funny. Pieces of wood "floating" a few feet above the water surface. The rest of the movie is pretty crap too as expected, horrible acting, horrible script, horrible cinematography etc. But the CGI alone makes it worth a watch and a good laugh.
