…if you waited for an affordably-priced domestic UHD release for Phenomena, Synapse Films has amply rewarded you here. You get all three versions of the film in sterling presentations plus an impressive slate of extras that take you inside the complex story of this film's creation.

Argento treats his storyline as a springboard for stylization, mixing delirious horror concepts (a giallo-style killer, nightmares becoming reality, a "thing" chained in a room, a family house with secrets, swarms of insects) with lavish visuals that utilize everything from swooping crane shots to underwater photography.

Though it stays true to the narrative conventions of its chosen genre and is not as formalistically wild as Suspiria or Inferno, Tenebrae has a heightened visceral impact and some interesting new thematic preoccupations that keep it from feeling like a retread.
