One issue with many Czech brutalist buildings is that they are brutally impractical - no heat isolation, mold problems, clogged toilets, not enough natural light, not accessible for the disabled, hard to repurchase, slowly falling apart yet using many custom parts that are no longer available & and the buildings are like 50% made of asbestos by weight. They might look impressive from sufficient distance, but often not very useful.
