Arrow's Dolby Vision presentation features a heavy amber push early, then intense blues at nightfall. That's not different from previous Flatliners discs, although this warmth looks and feels decidedly digital, certainly modern. Given the often darker cinematography, faces turn absolute red in places. The blue tints fare better in comparison, nearly monochromatic or not. It's a lot, surrealist intent or otherwise.

Other than the saturation, Flatliners looks superlative and suitably glossy. Grain replication doesn't waver, keeping the imagery crisp, natural, and film-like. High-end sharpness brings substantial detail, especially in close. Exteriors show stellar definition, whether brick or concrete. There's little doubt this is a true 4K scan.

Against the pure black shadows inside the lab, spotlights shine. Dolby Vision adds that spark, vivid and intense. Peak brightness doesn't enjoy subtlety, bringing the same generous pop to medical equipment screens or any other such objects. There's no loss to the darkest parts of the frame either.

Audio

Splendidly using the rears to enhance the score, music bounces between the speakers wildly during the death visions. Sounds swirl around, sweeping the soundstage aggressively. Jolts from various electrical shocks hit each channel.

Deep (if unspectacular) bass adds weight to the music and the visions. Consistent range commits to every opportunity. Arrow also offers a DTS-HD stereo track without the same power. Stick with the 5.1.
