Sure. I understand that. I love movies like the Hustler and Paths of Glory and I don't know much about pool and military justice. But Endgame, Loki and What If spent literally HOURS talking about the mechanics of time travel and alternate realities, and from what I read online a LOT of people still don't understand what the difference between timelines and universes in the MCU. If the MCU is gonna be doing this multiverse stuff in the future, I think it's important that it has somewhat easy to understand rules to make sure things don't get out of control. I actually really enjoyed how Quantum Leap and Bill & Ted handled this kind of thing (and in a REALLY humorous way I might add). I don't feel the same way about the MCU, unfortunately. But that's just my HUMBLE opinion. I have read numerous comments online that viewers just didn't understand the whole "timeline" stuff from the MCU. They might as well have been trying to comprehend the works of Heisenberg, Planck, Einstein and Hawking unfortunately. I was actually one of them myself, but I did some reading on MCU multiverses, so I'm sort of up to the speed on this stuff, but I imagine some audience members just gave up. Which is something I don't think Marvel Studios could possibly desire.
You're actually probably absolutely right in saying that magic users in general know how to use runes. You have to forgive my almost complete ignorance about written and spoken spells in fiction. As you've seen in my previous comments on these matters, I'm kinda ignorant when it comes to comic book mysticism. I'm grateful that you, DigiCom and Clea have been REALLY patient in explaining these aspects of magical storytelling to me. To me, I just think seeing calligraphy written in the sky glowing like beacons looks incredible!
