About the fashion, I agree somewhat, sometimes looked more like workout clothes. But otherwise, I disagree. She's quite versatile. I loved the torch songs about her unrequited love. Bathwater is still one of my favorites. And the way she sang them was/is amazing, too. Oh, and I did like the pink hair. Not a look for everyone, but it worked for Gwen the singer.
Oh, I didn't have a problem with them per se; I just thought the songs were ubiquitous. It was obvious for awhile that she was a girl with issues, so, I'm glad she moved on. We all do. I'm also glad to say her issues never dipped to Madonna lows!
