^^^ Ok, but you aren't talking about poorly designed retail, you are talking about how brutalism = negative feel for occupants. The idea that brutalism = bad retail is categorically wrong.
You can be blind to the resurgence of Modernism and Brutalist influences all you want, but a wide array of the most popular architects are designing essentially Neo-brutalist buildings. The one that comes immediately to mind is Ralph Johnson:

And that's just one architect in one city... There is definitely a new strain of brutalism and it is alive and well. I never claimed is going to become
the style, but it is definitely rising in popularity again. And don't tell me only a few people like it because there is a whole cult in London that is obsessed with it.
PS there is an entire section in the Brutalism article on Wikipedia entitled "Resurgence" talking about how it has rapidly regained popularity over the past few years.
