How accurate is Ozamu Tetsuka "Buddha" with the real biography of Buddha?

Ozamu Tetzuka wrote a comic about Buddha. I read that and is quite impressed. However, some of the element may not be true. And based on what I read, I tell some stories in it, and my friends are offended. Some of the elements: 1. Parents of buddha pamper sidartha with women even when he was a child. Such act would be considered child abuse in western world though most males would think, "nice" 2. There are some characters that are obviously fictional. I wonder what are the differences between Buddha the manga and the "real" buddha? https://en.wikipedia.org/wiki/Buddha_(manga)
