A group of tsunami survivors find they've more to worry about than just keeping dry in this high-concept 3D b-movie; trapped inside a submerged supermarket, they also have to contend with a killer shark swimming up and down the aisles. Much better than the lamentable Shark Night 3D, this Australian flick is a fun watch and boasts some effective stereoscopy thanks to the Blu-ray's crisply-rendered MVC 1.78:1 picture. The DTS-HD MA 5.1 mix also has real bite, with strong dynamics and good bass presence. Extras take the form of a 44-minute Making of… and the trailer.
