WTF dude. Metro is ALL about content forward and pushing style aside. For instance live tiles tell you when new email has arrived so you don't have to click into the app if nothing is new.
You might not agree with that approach but at minimum don't just make things up...
Live tiles are well done in Win8, no complaints there.
WinRT apps are a problem. The usual recommended style of WinRT apps, including built in ones are characterized by low information density, i.e. inefficient display of information.

The UI is designed to look clean, but does not display the information needed to work with it. E.g. you have to guess that certain elements require moving the mouse into corners and perhaps right-clicking to reveal hidden menus.
