As interesting and impressive of a task that is Jonh … I am the guy who hated everything about Rebels so anything that plays tribute to it, especially the “World between Worlds” and Time Travel crap … it’s a nope for me.
I too disliked Rebels, and hated the time travel, but the World Between Worlds itself I actually really like. It plays into the mysticism of the Force. Just because a show is bad doesn’t mean there aren’t good elements within it.
To be fair, there’s no real time travel that occurs through the World Between Worlds. It can’t be used to, say, change history, because from our perspective, any changes made – like, say, Ahsoka surviving – were always made. It’s strictly a closed loop. We see Ahsoka survive at the end of the original Malachor episodes, we watch how she survives in the World Between Worlds episode, and she’s returned to her original place and time. She isn’t pulled forward at all.
