Yeah, it seems Ms. Marvel will have a different tone than the other MCU movies. And that's fine with me. The MCU has avoided "super hero burnout" by delving into different genres.
Obviously, we wouldn't expect a Punisher level vibe of dark, gritty hyper-violence from a young teen coming-of-age story. If you want that, then check out The New Mutants.
So, it's going to be more attuned to the aesthetics of Y.A. fare. Which won't be for everyone. But it seems to be designed with the hope of reaching a new generation of fans.
Which is exactly what the comic book version of Ms. Marvel was doing.
