I think the thing a lot of people overlook when critiquing any kind of architecture is that for every architectural style there are good and bad examples. Sometimes, we focus too much on the bad to the detriment of the good.

I have often felt that a lot of the hate for 60s/modernist/brutalist architecture comes from the stand out bad examples. For example the works of John Poulson, an inept architect who landed loads of massive and lucrative contracts because he was really good at bribery. His practice churned out building designs at a ferocious rate and while some are considered decent (e.g. Leeds International Pool) the vast majority are just bland, soulless blocks designed and built to a price point. Many also had serious structural issues too.

There is a lot of modern architecture to love and appreciate if you can filter out the bad.
