I can't believe theres so much love for Jules and Verne. You realize they were shown for about 30 seconds in the trilogy and neither had a line between them.
Yes, it has been all about Marty, and the strangely repetitive situations he keeps getting himself into. All with the same elements showing up in a slightly different manner.
And if they were to do that any much more, the franchise would quickly turn into a sad parody of itself. That right there is reason enough to stop and leave it as it is. Otherwise, it has to evolve in one direction or another. (Actor's conditions is another reason to shift focus from Marty, but isn't as important in anything that isn't live action).
As for the kids, it's not about any development they had at all. It's all about potential. As the Doc's kids they are already pretty important to start with, and they've grown up with unique access to time travel, so they kinda happen to be in the best position ever for this sort of thing.
I've brought up other aspects of this in threads before. Like how they've got to have had the coolest childhoods ever. They even spent their early years stuck in the 1800s, so you know this crazy stuff didn't become mundane for them. Also gotta wonder just how much doc passes on, because of how dangerous he views time travel. And that the cartoon did quite a bit with them. Yeah, I know, it was silly, but whatever.
At the very least, it's hard to hate steampunk.
To a lesser extent, Jennifer is another character who doesn't have enough involvement in the plots as she should.
