So many obvious questions were left out

The whole series was very well made, but I kept wondering why they left out so many obvious things of the story, like:

1. We never really got to see just what it was that Bhagwan was actually preaching! There's just endless accounts of people saying he's supposedly oh so great, but the series never really tries to make us understand what made people so crazy about him. What was it that he actually said that was so revolutionary? This is such a major flaw, that it kinda breaks the whole premise before it even starts.

2. They never explain why everyone was wearing red. It's a major detail throughout the whole show, and it would have been extremely easy to just have a short sentence explaining it, so I found it extremely strange that they left it out.

3. They never actually confronted Sheela with anything! Every time there was a huge revelation, like the poisoning, the assassination attempts, the wire-tapping, or the secret basement, I was dying to hear what Sheela had to say about it. But they never asked her about any of it.

4. They never ask any of the Christians if they see the irony of claiming their own religion is the one true way.

I'm sure there were more stuff too...
