A masterpiece, surreal-absurdist-comedy, every frame of this picture a portrait of people lost in a dystopian past/present.
While the Wikipedia offers spoilers it might also help you to figure out where you are in the film: https://en.wikipedia.org/wiki/Playtime
Like the central charcter - ish - Monsieur Hulot - you'll periodically find yourself lost in the labyrinth of glass, reflections & concrete. Lots to unpack here and rest assured you didn't unpack it all in the first viewing. Brilliant in it's photography, location choices, lack of meaningful dialogue - the background conversations that tune in and out, direction it took to have quite literally dozens of people walking and performing on cue, it reinvents cinema and yet - the reinvention ends here.
I'd highly recommended this.
