OP here's the thing
even comics Carol got her powers from the Kree Mar-Vell originally and was, yes, just as powerful as he was with the same powers as a consequence, and he was Superman-tier (being a deliberate homage to his Fawcett Comics namesake that DC had run out of business more than a decade earlier for, you know, being a Superman-like character)
eventually she was shown to be even more powerful - as Binary - and as a human/Kree hybrid (thanks to the omni-wave projector that bound Mar-Vell's DNA to her own) there's really no reason to assume she wouldn't have powers not in the original's possession, especially given her history since then
but movies don't have literally a decade to make a Mar-Vell supporting character - who was already an AF major, former test pilot and head of NASA security in 1967's debut series - into a superhero in her own right; so they've apparently skipped ahead and used Carol - who is Captain Marvel now and has been for like, five years, since the ghost of Mar-Vell himself (not any of the various others who've held the name) said she was worthy of the title
so as a comic book reader, I'm perfectly fine with this
it's a manipulation of comic book canon, sure, but what isn't? what original stories do any of the X-Men movies stick slavishly to? did it matter that Don Blake was a real guy whose clothes Jane just happened to still have around instead of a goofy alter-ego? what fucking Batman vs Superman comic - and there's been plenty of those - has them kiss and make up because their moms have the same name? have you been crying yourself to sleep because Cap survived Civil War? do any of the TMNT movies or tv shows resemble the original comics more than superficially? why would anybody buy a comic as bad as the Green Lantern movie, month after month?
it's a Captain Marvel movie
fuck, I mean at this point we don't even know that she's *not* a Kree called Mar-Vell using the cover name "Carol Danvers" to infiltrate Earth
