Just trying to drum up some hits for the 'ol twitter and "talking head interview" circuit by being ******, I imagine. It's why a third of the actors in hollywood even open their mouths most times... another third are yapping to try and virtue signal to their fellow bubble dwellers, and the last third are generally quiet.
I'm looking forward to it, even if it's a bunch of kids/"the next generation". I had no problem with them making the 2016 version, in principal, and it even looked like it could be fun overall; it just turned out to be bad. I'm sure they could have done a good ghostbusters script with those actresses playing the same character, it just didn't pan out.
I'm more than willing to give this one as much or more of a chance, and hope it comes out enjoyable. I think one of the important things they'll need to do, is to tell a different story. I'm not a detractor of the new star wars movies (gear shift, bear with me, I'm bringing it back around), but I'm also not blind, and could see that #7 (and to a lesser extent #8) were mostly just trying to recreate the same or similar events from 4 and 5 (even using the same plot points in most cases), and I everyone I know, believes the films suffered for it.
For that reason, I think GB3 needs to tread new ground (and I don't mean "give each character their own special "proton shotgun", or "Twin Proton Pistols"). Take the premise, write a new story, have new characters.
