Sometimes it looks really cool and I find myself playing with the UI just to see what happens, sometimes it looks so ugly and terribly antithetical to the idea of a cohesive design that I miss the previous design language significantly. The phone is a tool I use.
Remember that iOS 18 was over a decade of evolution on the design changes in iOS 7, which also had a significant amount of hate when it was released for being ugly, confusing, and hard to read.
