Frank Ritz’s review published on Letterboxd:
Without hyperbole, and putting personal feelings aside, I think this is one of the Ten Best movies ever made; certainly one of the most important. But to expand on this further only ruins the purpose of the film instantaneously. There's something elemental, mystifying, and insoluble happening within the frames; it's one of the few [true] Rorschach tests ever put to film. This is the film that understands the most how to involve an audience into the watching of it, and that each viewer is able to bring their own baggage, ideology, and preferences, to the film, and everyone will see something different, and unique, at the end of the run time; while skirting past being experimental/completely abstract. I feel like I know exactly what happened in the "story" (and it's not what I see most reviews saying), and yet, it doesn't even matter remotely, because this is a metaphorical tale about classism... or is it? It's a staggeringly confident work, that takes it time, to slowly burn away all the preconceptions of what we think we know, and truthfully dig down into the one thing that defines all reality; perception. It helps that Lee Chang-Dong is an incredibly talented director with vision, and a writer full of control, and that the leads are incredibly impressive; doing some of the best work of this decade (if not all-time (Yoo Ah-in and Steven Yeun both win their categories for this year in my book, and Jun Jong-seo easily would've if Tilda didn't have Suspiria)). It's beautiful to watch, and listen to, and it functions as a mystery; not a solvable one, but with how it sucks the viewer into it's world, and doesn't let go until it's final seconds, and even then, it still lingers.
This should be the future of cinema; it belongs in what I call the Vertigo lineage (i.e. understanding the path/history of film), while simultaneously forging new grounds to trek through (this is guaranteed to be more successful than any direct attempt at a choose your own adventure type film (a sub genre I think we are headed towards)). I wish all films could be like this (a sentiment I've written in reviews three times now (High and Low and The Big Sleep were the other two).
EDIT: This was my third viewing, and it literally only gets better every time.
