Why do Gen Z/Zoomers love the 2000s but Millennials hate it?

I have seen the claim how millennials really despise the 2000s decade as a whole and they hated the aesthetic of that decade. While gen z/zoomers like me remember the 2000s in a more positive and fondly manner. What is it about the 2000s as a decade that made millennials hate it, but gen z/zoomers love it and why?
