"47 Meters Down: Uncaged" follows the diving adventure of four teenage girls exploring a submerged Mayan city. Once inside, their rush of excitement turns into a jolt of terror as they discover the sunken ruins are a hunting ground for deadly great white sharks. With their air supply steadily dwindling, the friends must navigate the underwater labyrinth of claustrophobic caves and eerie tunnels in search of a way out of their watery hell. (Gary Reber)

The 2.39:1 1080p AVC picture, reviewed on a Sony Bravia Z9D 4K Ultra HD HDR display, upconverted to 2160p with greater resolution and luminance, was photographed digitally using the Arri Alexa camera system and sourced from a 2K master Digital Intermediate format. The underwater imagery is effectively photographed and conveys a constant sense of the unexpected. The danger plays on the underwater cave's darkness and claustrophobic labyrinth and dependency on the characters' diving gear. Lighting effects, which cast green and blood-red hues through the water enhance the sense of being attacked. Black levels are deep and shadow delineation is decent given the extremes of the no-light underwater caves. Above water the imagery is crystal clear with perfectly natural and vivid color fidelity. Hues are nicely saturated and fleshtones are consistently natural. Resolution is superb with fine detail exhibited throughout. This is a compelling visual experience that is emotionally impactful.

The DTS-HD Master Audio™ 5.1-channel soundtrack is intense with a virtually constant deep bass presence that extends to powerful sub-25 Hz, with moments of sharp SPL bursts. The synthesizer score further intensifies the danger and threat of death by shark or drowning, The constant sound of the air tanks tripping air bubbles also dramatically creates a threatening presence. Surround envelopment is virtually constant with atmospherics and sound effects extending aggressively to the surrounds,. The music envelops the entire soundfield. In one segment the music reverberates throughout the cavernous underwater soundfield. Dynamics at times are powerful. There is a segment, which just pounds and pounds with intense sounds of .1 LFE-enhanced rushing current. Dialogue, including a lot of screaming, is remarkably intelligible given the setting and is generally spatially integrated. This is a frighteningly active holosonic® soundtrack that delivers on the sense of intense terror. (Gary Reber)
