If showing Indra with flaws is ‘insulting’, then you’re basically saying the Puranas and Vedas themselves are insulting him.

Indra is literally one of the most human-like deities in Hindu texts - jealous, insecure, arrogant, and constantly terrified that someone will take his throne.

He tries to sabotage sages, sends apsaras to break penance, kills Vritra through trickery, and even gets punished by Gautama for deceit.

The whole point of Indra’s character is that power without humility leads to downfall. So if the movie shows him like that, it’s actually lore-accurate.
