Postmodern novels are some of the hardest to adapt. The hope is to subvert linearity without propelling head-on into the unwieldy avant-garde. Like trying to adapt a Wallace, Franzen or Pynchon novel, this project is just out of reach for an ambitious low-budget project.
I want to give this -1 star for making me need to get the guts to keep on watching it without being able to sit through five consecutive minutes. it's just like antonioni's blow-up, except that one made a lot more sense and was just generally very well made. this is just about a guy that's an asshole (though no one recognizes it) and tries to prove a pseudo-intellectual point by being an asshole.
Tom McCarthy's eponymous novel is a masterpiece. Alas, this adaptation simplifies & dilutes the original story relying on a narrative gimmick (the loop) to inject some (weak) coherence. An unfortunate decision. Denis Villeneuve took Saramago's "O Homem Duplicado" and transformed it into something incredible (Enemy). Fast just wasted a great opportunity. I hope that Satin Island will be directed by someone else.
