It looks a lot like a more realism-drenched version of Vincenzo Natali’s claustrophobia-inflected 1997 feature Cube, with a similar sense that there are a lot of grand, echoing mysteries to explore.
Galder Gaztelu-Urrutia’s feature-length debut is a supremely confident genre mash-up that fuses the mysterious-prison conceit of Canadian classic Cube with the tongue-in-cheek social commentary of Bong Joon-ho’s Snowpiercer before slathering it all with torn strips of flesh and buckets of blood.
There are ways of making this work, presumably; the film isn't so far removed from the cult classic Cube from 1997, which if anything makes even less sense as anything but an extended metaphor.
A pitch in search of a movie to ground it, Galder Gaztelu-Urrutia’s The Platform never amounts to more than the sum of its parts, but fans of high-concept science fiction such as Cube and Snowpiercer may nevertheless appreciate the sheer number of those parts in a film that teems with ideas, but ultimately fails to commit to them.
However, if you’ve seen “Snowpiercer,” not to mention “Cube,” “Saw,” not much feels fresh in “The Platform,” its “bottle” concept not necessarily new cinematic DNA ditto its upstairs/downstairs socialist allegory.
Much like 1997’s Cube, his film never looks chintzy.
