Metro is pulling things in the right direction I think. Hyper-skeumorphism did immense harm in the hands of copy-style designers, allowing them to justify their unoriginality through "I can copy that because it's actually copying a real-life object, you can't be unoriginal if you copy physical reality, all great artists did it" reasoning. It's better to concentrate on the axis between obscene skeumorphism and uberminimalistic full-flatness then to pick on any one of the extremes as they are obviously flawed.

Take for example the whole crop of metro-style Bootstrap themes and pick an UI interaction element like the buttons, to see an example of a scale of designs between decent micro-skeumorphism and full-flatness. This one http://bootswatch.com/cosmo/#buttons or this one http://talkslab.github.com/metro-bootstrap/basecss.html#butt... sport full-flat microsft style buttons, with no hints of possible interaction, while others like http://inprogress.neuronq.ro/madmin/ show subtle hints of skeumorphism (you can probably google for many other more or less metrofied bootstraps...)
