Even the residents don't like them:
>>“There isn’t much design inspiration. They’re just stacked up,” said Park In-seok, an architecture professor at Myongji University. He described a paradox in which the apartments are mocked for their appearance but coveted for their convenience. “Almost everybody hates the apartment,” Park said. “But everybody wants to live in one.”
>“But everybody wants to live in one.”
This was the part that I didn't understand until I experienced it. If they were more visually appealing from the outside, and in the stairways, people may stop hating them.
The small town my wife is from in the North Caucasus region of Russia has green everywhere. It also has schools, kindergartens, small grocery stores and parks within ~5-10 min walking distance of pretty much the entire city and public transit everywhere, roughly one bus per route every 5 minutes.
Sure the buildings are arguably uglier but the area as a whole is beautiful and far more livable.
I grew up in the American suburbs and now live in Manhattan. I hate American suburbs with a passion. Inconvenient, car-dependent, and isolating. NYC is great, but the apartments here are old and terrible by modern standards (not to mention the decrepit subway).
The problem is that America seems to care more about aesthetic appearance than actual living conditions. I don't think anyone will disagree with you that those Soviet-style blocks of identical apartments are ugly from the outside, but I'd rather live in a modern high-rise than some shitty 100 year old 5 story tenement walkup, or some giant house in the suburbs where I can't get anywhere without a car.
