Peter Bradshaw at The Guardian:
Memoria is a beautiful and mysterious movie, slow cinema that decelerates your heartbeat. For some, the andante tempo, with its glacially long silent takes, will exasperate – and opinions may divide on the extraordinary sci-fi epiphany ending. Even now I’m not sure what I think about it. But what originality and daring, the biggest ideas invoked with compelling zen humility.

But he approaches these phenomena as calmly as he might questions of agriculture or engineering.
