I think it’s fine. It definitely needs some polish and there are other, unrelated changes like the big round corners that I dislike, but Liquid Glass itself is just… different. And appearance aside, I genuinely like some of the updated UI patterns, such as making buttons look like things you can interact with instead of undifferentiated text.
It’s OK to dislike glass, of course. I’m not saying doubters are wrong. A lot of it, though, feels like piling on to sound like one of the cool kid skeptics.
