First and foremost it's unnecessary and is not fixing anything.

Second, it forces learning a new layout and system. I don't understand instead of gradual changes in UI to improve experience they went with whole new thing.

Third, it's slow, bloated, and really hard to navigate through. Old version can display more pertinent information per screen resolution.

In a nutshell, hinders user experience without any noticeable improvement.

Finish product is bad design because initial idea was bad design to begin with (i.e. the idea to fix nothing and break everything).
