I just went through the Hinduism course and it was an amazingly deep insight into how the country of India works and worked in the past when it comes to social fabric as religion is quite tightly weaved into the culture.
It is much much better than any of this fancy high production value celebrity tabloid thing we call "MasterClass". Nothing masterful about it.
I would recommend reading the book 'Being Different' by Rajiv Malhotra to balance out any such courses on Hinduism.

Explication of local culture in a foreign language for the benefit of foreigners will also have a slant. But it will be a very different slant, and it's a lot more accessible than the native materials. If the goal is "deep insight into how India works [today]", then Being Different is probably a pretty valuable thing to read even if the scholarship is shoddy. (On which question I have no opinion whatever.)
