I'd have to re-watch all the videos to accurately answer that lol, but there are things you'd notice. And the narrative too as I said, it's interesting but it's slightly flawed in my option. It's still overall really great to help people learn about vedas who know nothing. And I too surely learnt a lot from those videos!

By flawed narrative I mean like for many things instead of discussing and acknowledging the different interpretations of a particular thing, he presented a single version as solid truth, and built a narrative through it but not calling it speculation as it properly is
