Oh, I know this. My dad is, well, a decade older than you, but I'm in a business run/flooded by 40-55 year-olds (most of them into comic movies and sci-fi like Star Wars and Star Trek). I know he's Solo to you guys. I never heard anyone say they're not going because Ford didn't star in it, though. That's a new reason to me.
There's a massive difference between inclusion and exploiting. TLJ wasn't inclusive with good reason - it was exploitation for profit. Is there a logical reason that Purple Hair Lady was granted a sacrifice while Akbar was killed off-screen? Not that I can think of. Why Vice Principle Strong Woman instead of Leia?
I didn't bat an eye with Boyega as a new and main character. Why? Because his character, in TFA at least, was well-written. It has nothing to do with anti-inclusion, but rather, anti-exploitation. Big, massive, difference man.
