Screen described
Luka as "atmospheric" and "visually arresting" but "dramatically unengaging", with a second half that plays "like an arthouse-oriented, lo-fi cousin of
Denis Villeneuve's
Dune". Jonathan Romney of
Sight and Sound wrote that the film succeeds at looking otherworldly but fails to captivate viewers through "an antique flavour of Europudding in the mix of accents" and "sometimes impassive, sometimes overstated acting that loses its energy in the sound mix". ==References==
