This is my objection also. Sturgeon's Law says that most things are bad; it doesn't obligate anyone to celebrate those failures.

Having spent time in quite a few 'iconic' Brutalist building, my experience is that they're frequently terrible. Impressive looking, but deeply unfriendly to their inhabitants. There's one where it sometimes rains indoors because the venting and vault-ceilings are so poorly executed. It's still lauded as great architecture.
