Hawass remains an expert of contradicting himself, did he not at the end of the documentary uncover the enclosure wall of a pyramid complex discovered with the satelite technology?

I don't think 17 pyramids is an exageration; Sarah Parcak stated that these 17 also included smaller pyramids of queens and princesses. Size, orientation, location and layout of the potential pyramid(-complexes) were taken into account. No exageration or nonsense IMHO.
