People don't like Kenny G because they're "real musicians" who don't understand that their idea of "real music" is fundamentally uninteresting to the general public. I give immense props to Kenny G for keeping at least some form of Jazz relevant after the post-bebop era's digression into more and more academic, aesoteric and difficult music.
It goes without saying that smooth jazz has a place and purpose, not only in and of itself but also as the inspiration for a substantial part of new music being created today - the vaporwave movement is almost entirely comprised of smooth jazz samples, mainly from kenny g and his contemporaries.
