When it comes to translating their comic book properties to non-comic media, Marvel has done a darn good job when it comes to the compromises which have to be made. The way costumes look... the way powers work... the way continuity has been built... choices have to be made every step of the way, and there has been shockingly little that I've not felt was smart, cool, and appropriate.
Ms. Marvel, based on a highly successful character from the comics, is an American girl of Pakistani Muslim heritage who idolizes Captain Marvel and wants to be a super-hero just like her. Then one day she gets her shot, and her life becomes a balance between being a hero and being a girl trying to fit into her life and school while still holding true to her family's traditions and values.
In the comics, Ms. Marvel is a "polymorph" who has the ability to stretch and embiggen parts of her body. She got her abilities after being exposed to the Terrigen Mists, which is how Marvel's Inhumans characters gain powers (meaning that Ms. Marvel is technically an Inhuman).
In the television series, Ms. Marvel finds a family heirloom (a "bangle") which gives her the ability to make cosmic energy constructs. You can see it on her wrist here...
Now, even though her powers are very, very different in the MCU, she still uses them in a way that harkens back to the comic books. If she wants to catch somebody, she generates a giant hand out of cosmic energy and stretches it out to make the catch. As opposed to making her actual hand grow to giant size and then stretching her actual arm out to make the catch.
I know some fanboys are going to be upset by this change, but I think it's pretty smart. First of all, her powers look kinda ridiculous in the comic books and probably wouldn't translate very well to television and movies. Second of all, part of her powers is basically a copy of Mister Fantastic's stretching abilities, which means that the Marvel Cinematic Universe would have two people with a confusingly-similar gimmick once The Fantastic Four movie arrives.
Which is to say that the MCU Ms. Marvel is more "Green Lantern" than "Mister Fantastic."
I'm not sure if I approve of the whole "cosmic bangle" source of her powers, but the powers she has been given I definitely approve of.
I also approve very much of the show itself.
Ms. Marvel streamlines the comic book narrative into something that works for television very well. The core aspects of her character are very much the same, and that's more important than most anything else because it's those aspects which make her unique.
Visually the show is quite good... using auxiliary graphic elements to give the series a unique flavor and make it fit the youthful vibe of the character.
The cast is phenomenal. Iman Vellani IS Ms. Marvel, and they fill out her family, friends, and acquaintances with equally-capable actors. It seems as if Marvel Studios is simply incapable of making bad casting decisions...
We've only gotten one episode to look at, but the storytelling is on-point and things move at a brisk enough pace that the episode doesn't feel bogged down (as what happens with so many origin stories). But the best surprise of all? MS. MARVEL IS ACTUALLY IN THE SHOW! After the way Moon Knight had practically no actual Moon Knight in it, I was mortified that this might be a new trend. But nope!
I don't know that Ms. Marvel will overtake Hawkeye as my favorite MCU Disney+ series... but maybe it will get there. The pieces are certainly in place to make it a fantastic show, so fingers crossed.
