It's a pretty typical Relix review. . might even run a little on the long side. ;) 
I don't mind that Mr. Adamian makes comparisons to other powerful well known female artists - others have done the same.  It may catch the attention of some people who aren't familiar with Grace &amp; GPN and make them curious enough to try the album.  I don't think his intent is to be negative when he infers that Grace is still evolving as an artist . . interviews of late might suggest that Grace would even agree with him.  
My problem is that there is really no critique of the music on the album.  So I agree with Eric . . the Relix review style is a bit lazy.
