Who is still talking about Buffy? She's been out of the public conscious for more than a decade and has no media follow up that continued her story.
That's not technically true. The Buffyverse has been continued in a popular line of comic books that are plotted and supervised by Joss Whedon and are thus considered canonical. Comic books are a medium, therefore there has been media follow-up.
Kamala captain marvel? that's comic marketed as the muslim Captain Marvel right?
Carol Danvers is Captain Marvel now. Kamala Khan is
Ms. Marvel, taking over Carol's old code name.
and why add more religion into comics?
Kamala is not defined solely by her religion just because her religion happens to be different from yours. She's defined by being a fun, exuberant, youthful, believably nuanced character who's captured imaginations in a way not unlike how Spider-Man did in the '60s. The fact that she also happens to be a Pakistani-American Muslim is just one facet of who she is, because immigrants and people of diverse religious and cultural traditions are a facet of American culture, and it's ignorant and dishonest to pretend that they aren't. Should Ben Grimm and Kitty Pryde be excluded from comics because they're Jewish? Should Nightcrawler be banned because he's Catholic? Should Superman be banned because he's Protestant? Heck, Wonder Woman is an
actual demigoddess, in her current interpretation. She doesn't just worship the Greek pantheon, she's related to it.
Most of the creators of the seminal comic-book characters we value today -- Jerry Siegel, Joe Shuster, Joe Simon, Stan Lee, Jack Kirby -- were the sons of Jewish immigrants. They grew up facing persecution and intolerance every day because of it, and they were inspired to use their comics to portray a better world, a world where outsiders and misfits could be heroes and could take a stand for the equal worth of all peoples. That's something we need today as much as ever, when Muslim Americans are being victimized by racist demagogues exploiting the ignorant, just as Jewish Americans like Lee and Kirby were back in the '30s. The American way includes Americans of all faiths and heritages. That's been the message of superhero comics from the beginning, even before they were able to say it openly.
and when did DC or WB allow Wonder Woman to carry her own show?
wasn't she just an extra wheel in the justice league toon like Green Lantern and everyone else in the teams?
Actually, for a long time there was a policy in place that Wonder Woman couldn't appear as a guest star in any TV or film adaptation, that she could only be used if she were a lead character. This was meant to raise her profile, but it backfired because it kept her from showing up as a guest in other heroes' shows, and so she got less exposure. She only got to appear in productions where she was either the sole lead, as in her 2009 animated movie, or one of the stars of an ensemble, as in the various Justice League productions. (This is why she was the only member of the Justice League who never guest-starred on
Static Shock.) Luckily, that's no longer the case, which is why she was able to appear in
Batman: The Brave and the Bold and
Young Justice and why she's about to appear in
Batman v Superman.
So it's incorrect that she was an "extra wheel" in
Justice League. The only reason she could appear in it at all was because she was equal in status to the other six leads.
