I think the MCU has done a pretty good job of "grounding" the craziness of comic book stories for the first three phases. That's why I favor the movies and shows to a certain extent. Even Strange's magic in that first film of his didn't feel too ridiculous to me. And he was using an Infinity Stone when did his magic. For a long time I thought Wanda got her powers from an Infinity Stone as well, but her show clearly stated that she was "born" with the power of Chaos Magic. Then she was able to create life, manipulate reality (as well as time and even the WEATHER), while mind controlling thousands of people. To me, Wanda is starting to get a little overpowered. I think Strange is a bit too with him casting spells to make probably MILLIONS of people forget that Peter Parker is Spider-Man. I prefer their powers come from "cosmic gems" and/or "other dimensions" and/or using "dangerous artefacts" and/or being "possessed by powerful demons." So it's not totally THEM that's doing weird shit. I guess that's what I meant by comic book-y. I'm actually wondering how the HELL is the MCU gonna make dudes like Ghost Rider and the Silver Surfer NOT overpowered when THEY are introduced. I actually don't mind if the villains and antagonists are more overpowered though. Especially if it takes a team of heroes to defeat them.
I sorta understand where Aaron was coming from. Because many people feel that "magic as a storytelling device is a disaster waiting to happen":

I read an old interview on CBR that Aaron participated in, and it discussed the "rules of magic" in the Marvel Universe:
https://www.cbr.com/interview-aaron-...ngoing-series/
"At the Marvel retreats we have a couple times a year, a lot of times we'd talk about magic. How do we deal with magic? How do we portray magic? What are the rules of magic? Those were kind of long conversations where we didn't really settle on defining magic -- and I don't think we need to. I don't think we need a huge set of rules for magic. For me, there's just one rule that's very important, and that's that everything that Strange does has to have a cost. There has to be repercussions when you gamble with these kinds of forces."
"Exactly. I don't want a Doctor Strange who is a deus ex machina. I don't want him to show up, wave his fingers around, say some weird words to save the day, and suddenly everything is fine. I want a Strange that really has to fight and suffer for everything he does."
Having a cost to magic is a simple rule that limits what magic users can do. I think it's a pretty cool concept. Though going on disgusting magical "diets" might be too much for the MCU too handle.
