What sadistic scares fester beneath forgotten battlefields or failed utopias lost following sweeping conflicts shaking civilized society’s foundations? Underground tantalizingly invites such provocations by plunging unsuspecting bachelorettes into subterranean depths housing WWII era secrets below vacation vineyard soil. And the central conceit of innocents trapped undergoing psychological corrosion while confined makes for disorienting found footage rich in textured atmosphere. But the script swiftly abandons ominous opportunity for distinct wartime tie-ins beyond initial setup. Failures tunneling towards resonant themes leave subtle strengths found lacking necessary excavation reaching full distressing potentials promised by such fertile frightened ground.
After some cheeky jump scare prologue misdirection, Underground drops viewers alongside bride-to-be Emma (Amelia Tan) and increasingly anxious friends Karla (Jessica Clements) and Jo (Daniela Dibly) celebrating Emma’s final days before matrimony. Their wine country retreat finds dark turn when a vineyard bike ride reveals a series of ominous tunnels Emma insists on amateur spelunking straight from horror movie Warning 101 manuals. After seemingly supernatural interference, the trio find themselves lost and divided across miles of Labyrinthine military architecture and bunkers dating back to regional WWII infantry.
Claustrophobic cinematography captures panic and breathless confusion once disorientation sets in and splintered groups struggle navigating unrelenting darkness with only dying phone flashlights and night vision cameras illuminating unseen threats. Director Tom Paton builds relentless nervous energy through violently shaking passages and corridors that echo with screams yet restrict any wider orientation. And for awhile the sensory manipulation proves effective getting under the skin as Emma, Karla and Jo unravel both externally and internally while their scholarly historical host conversely embraces locked spaces meant protecting soldiers now housing the lost and hunted.
But set bound strengths find themselves watered down the further Underground strays from initial battlefield remnants and wartorn backstory holding unique storytelling potential. Weaving ghostly guessing games through the compound about whether spectral forces or disturbed squatters menace the missing women diffuses distinct despair such confined hopelessness manifests minus cheesy jump fakeouts relying on hollow hallucinations and thinly characterized breakdowns lacking compelling catalysts. And with no found footage visual texture or dated set decor stretches tying Underground explicitly back to wartime themes frequently hinted, an elevated Battle Royale theme centered on unwitting innocents combating situational chaos devolves into obligatory girl power bonding unexpectedly undercutting authentic anxiety sustaining what palpable tension surfaces.
Underground certainly mines universal fears like claustrophobia, nyctophobia and herd separation psychology sharpened within unsettling subterranean territory promising unique story exploits which go unfulfilled despite the dynamite setting. Capable directing and committed lead performances certainly elevate otherwise limp chase sequences down dark passageways or uninventively staged survivor standoffs in rooms looking lifted from Saw or Cube copycats lacking distinct identities. But the absence of clearer quasig hostorical plot relevance regarding military asylum legacy ultimately makes the entire ordeal feel like a missed opportunity for sociological statements, philosophical debates or moral conundrums confronting buried secrets of the past beyond the obvious.
With era-specific production design and costuming begging bolstering narrative weight only cursorily incorporated, the thematically resonant realm this decently crafted descent barely breaches denies audiences a smarter caliber of horror typically expected from highbrow streamers like Shudder or Screambox. Instead we’re left wandering lost through dimly lit rooms chasing the same scarred survivor tropes sought since Blair Witch solidified found footage without expanding format horizons or genre social commentary both ripe for reexamination.
In the end, Underground burrows towards immense possibility before backing away from bolder human horrors hiding behind enemy lines and veiled shadows deserving deepest spelunking. Claustrophobic sequences spark sporadic scares for those satisfied with surface tension treading familiar ground. But transformative genre greatness demands drilling down past easily accessible angles towards tectonic thematic layers richer than the hastily dug shallow grave this solid delivery unexpectedly embraces sinking into conformity rather than veering the unforgettable.
