I like how powerful she was. I like the visual aspect. I like that she was with the X-Men. And I like that her power came from a white hole.
I can see Marvel making her potentially as powerful as Binary in the movie. Her default power level would be less but she'd have the ability to power up.
Visially she won't look like Binary except when/if she's engaged in a serious power up. I'd like to see that.
We won't see her with the X-Men in this film for obvious reasons, but maybe eventually we can see her with the X-Men. Of course the best opportunity would be the very movie most of us don't want: X-Men in Space. Still, if Marvel ever does an X-Men in Space film, Carol Danvers would be a great guest star.
As for the white hole - I really wish Marvel would use that, even if only as a one-time deal. I'm a big fan of heroes stepping up to major power, even temporarily.
I liked her much better as Binary than Ms/Captain Marvel. However, what I didn't like is that they never really did anything with her. Although I've always liked Carol, the big thing I didn't like about her was that she was always in Mar-Vell's shadow. Binary had the potential to overcome this. Warbird too, but I didn't like the name, costume, etc.
I also preferred Carol with the X-Men or Starjammers than with the Avengers. To this day it pisses me off that the X-Men accepted Rogue over Carol.
