I dunno... the Yale Art & Architecture building is a classic early example of brutalism, and I've never been in a space that felt more open to creativity or so honest... it was a revelation the first time I stepped inside of it. I looked forward to classes there because it felt uplifting for my soul, and deeply envied architecture students who got to use it as their workspace, its spirit was so perfect.
Of course I'm sure brutalism can be done badly too (like anything), and I haven't spent time on the inside of too many others... but there can be something profound about it -- a modern building in balance that tries to be exactly what it is, no more, no less.
