Neo-Kabbalah as in what Berg teaches is bunk.
Chassidic Kabbalah from the teaching of the Arizal and then the Baal Shem Tov are authentic Jewish Kabbalah.
Without understanding the basics of Judaism, the Tanakh and Talmud, Kabbalah is nonsense... What the neo-kabbalah movement does is wrong and I join those who condemn it. But there is an authetic Kabbalah in Judaism, and this I believe.
