I give this episode a 5/5.

Hagoromo having a sharingan makes sense because:

1. His sharingan obviously eventually transforms into a Rinnegan since mixing a pure Sharingan with Otsutsuki Chakra grants one a Rinnegan (as seen with Sasuke). With Hagoromo it seems rather gradual.

2. Hamura started off with a Byakugan. By having his Byakugan and his Otsutsuki Chakra, it eventually transformed into a Tenseigan, just like Toneri. This process proves that the way the Byakugan and Sharingan evolve is related.

You have to give some props to Hagoromo for unlocking a 3 tomoe sharingan straightaway, though.

Also, we know another way to unlock the Rinnegan is to mix Indra and Ashura's chakra. I'm sure if Hamura had 2 sons, a way to unlock the Tenseigan would be mixing their chakra.
