Return to Grunge

What is this return to 90's grunge trend? I can't decide if I like it or not. I like the edginess the 90's grungesters exuded, but I think it could be translated in a more modern way...maybe mixing in some bleached, torn jeans with a more modern top, occasionally. As much I love the history of fashion I've never been too much of a fan of "backwards dressing."
