You mean the additional functionality? Have you actually tried using it?
Also, just for reference, people *****ed about the theme that is now called Windows Classic just as much for looking plastic and fake when it was new.
Some people just refuse to accept change. You hate the ribbon in office too, don't you? Even though it's faster, better, and easy to use for almost everyone, people always seem to complain when it is first handed to them. Yet user study after user study has shown that, after an initial adjustment period, people are actually FASTER using the ribbon than the old menu.
Keyboard shortcuts still win, though.
