Interesting fact: 2 of the 4 women who venture on this shark sequel have famous parents (Corinne Foxx, Sistine Stallone), but I can’t tell you if they survive. This time, the teen quartet takes a scuba exploration into a submerged Mayan City, where there happen to be hungry blind sharks. Several things hinder this from being better. So much of the action takes place in murky underwater labyrinths that it’s hard to tell what’s happening (and not in a scary way). Once the first attack occurs, what’s left is pretty much the same jump scare. Then, there’s the whole reality thing, which this plot continuously strains. The movie is never dull, it’s just not original or suspenseful.
