FWIW, I concur. He did find his audience, but it's just not Hindu enough for me. Just as I like my coffee black, I like my Hinduism with no additives.

The yogic powers mentioned by Yogananda has also been mentioned in the ancient scriptures and displayed by Krishna, Shankaracharya, Gorakhnath, Buddha and Mahavira.
In the present times they have also been displayed by Anandamayi Ma, Shirdi Sai Baba, Ramakrishna, Guru Nanak and many others.
I have witnessed these exhibitions myself and hence don't consider it fantastic as some who have never witnessed it and merely read about it.
As a Japanese saying goes,
' One look is worth a thousand reports.'
The astral worlds (corresponding to heaven and hell ) have been mentioned in the ancient scriptures too, and many of the Hindu rituals performed after death has to do with life in the astral worlds. For example, rice offerings are given to crows, who are considered as messengers from the higher dimensions.
In the Mahabharatha too, heaven and hell is mentioned, and that each soul enjoys heaven and hell in varying proportions according to the karmas they have performed.
Yogananda just elaborated on these astral worlds as he put it, which has been mentioned already in the ancient scriptures. And he has also stated the same after his interview with his resurrected teacher.
