Query: not her best

I have loved Christine McVie and her songs since she joined Fleetwood Mac. Her songs on Mystery to Me, Bare Trees, etc. got me into the group before they hit the big time, and her later songs, often along with Lindsay Buckingham got even better. So I am sad to say I am disappointed by this disc. Just not as good as her best. Many rock songwriters run out of creative gas, and it sounds like she has. I hope she can reinvent herself rather than try to rehash the same chords and lyric themes.
