apparently many has been confused by this movie.

Rating: 9/10 (4 January 2020)

A movie that makes one confused is often considered a bad movie. i suggest whoever reading this to first read the negative reviews, if i may.
this is entirely what i took of this movie, as what it is.
this very movie doesn't show a specific progress of time. and i take it that's why some people don't see 'any' progress at all. they confuse plot with time progression, thus with little to no hint of time they concluded that this is going nowhere. please allow me to make it simple to you: expect all events in this movie to take place within a week, and there are time skips when it's suddenly evening or afternoon, even the next day. (almost all of it is shot in a building so we can't look for the sky, and almost no clocks shown explicitly.) it's kinda detailed, shows what is going on behind the scenes, so with no cuts, it emphasizes that there is nothing that's not important here. (slightly arguable though, but i think so since that's we can see)
yes, maybe this movie is an impression rather than expression. but that often comes back to ourselves. see, there are people who looking deep into it to have a conclusion like "oh, so you wanna impress me. with {mentions what they do}. well, i can read into this so I'm not impressed". in contrast to that, i see this as a complete expression, as what it is. I don't look further as there's no need to guess. no idea to look further like Inception. no.
and this movie is good.
