I’m not sure how excited I can actually get for a Black Widow movie to be honest. Maybe it’s because I’m a fan of Marvel comics, but I’ve never seen her as a character that can really carry her own series (comic book or film). They’ve tried a couple of times giving her her own comic series and they don’t make it very far, this is even after she was pushed as the “main female” in the MCU.
You’ve got this universe with all these characters with a wide range of powers or skills that we could never witness in real life. So what makes an expert in espionage such an interesting character in this universe?
Their biggest problem is that they haven’t had access to many of the mutant females who could carry their own franchise and they keep tying the rest of their female heroes up in other franchises where they are playing background characters or sidekicks.
Then again I’m looking at the list of every female marvel hero and I know that the studios will feel like people won’t embrace characters like: Spider-Woman, She-hulk, Ms. Marvel, Ms. America, or Elektra. One will be percieved as a rip-off of Spider-Man (she’s not). One will be percieved as the female knockoff of Hulk (maybe she is, but she is a better defined character). One will get confused with Captain Marvel. One will sound like a beauty pageant winner. And one is probably wrapped up in the Daredevil show.
