Not much detailed observation on any religion that this TV series covered, except Christianity, which is too cleverly skipped all the bad deeds of Abrahamic religions, anyway I had a good time watching this, after few Episodes, the topic gets a bit repetitive and felt like lost from its track.
Btw Morgan Freeman, try to relate yourself more with your ancestor's land The Africas, never forget your blood-related ancestral homeland Africa, people should never forget their roots no matter how much they succeed in their life.
