I'm of two minds on this.
In general terms, I tend to think that we should stop making sequels to things, in many, many cases. Some stuff should just be left alone. Don't remake it. Don't do a prequel. Don't do a sequel. Just let the film stand as it is. That's not how Hollywood works anymore, though. After the prequels, I was REALLY dubious as to whether another Indy film could work. I remain dubios. I think that, unless you start from the outset with the belief that "This is a franchise and we will just keep making films until the wheels fall off, then retool and do it all over again," where you're cranking out films every 2-3 years like clockwork, you should not be going back to 20+ year old properties and trying to breathe new life into them.
With Star Wars, it's a little different. I see Star Wars as a setting, not as the story of the Skywalker family. In fact, I think the farther away you get from Skywalkers, Solos, and all the characters and settings we knew in the first six (eventually 9) "Episode" films, the better your stories can be. I LOVED Solo. But I loved it not because of the Solo character, but rather because of all of the other stuff it added. I loved the new planets, the underworld characters, the folks on the fringe of society, the Empire's battle on Mimban which we only barely touch on, etc. I similarly loved Rogue One, again, not for its connection to ANH, but because of the focus on people who were NOT the core heroes. I loved that it was basically The Dirty Dozen In Space. I loved the space combat as well. I want to see stories about those types of characters, and I think they can be set in any number of eras and settings.
But, to do that, I think you really have to break away from the "formula" of Star Wars....which is something that I think most fans and apparently some directors and a bunch of suits have difficulty doing. Like "Oh, well it's GOT to have white-armored bad guy goons. And the big bad guy HAS to be some red laser-sword-wielding guy in a black robot suit or something. And it HAS to have a huge superweapon and...." basically they just want to recreate what's already been done, only with slight tweaks on the theme. This is why I appreciated TLJ. My hope was that it would herald a real break from the "tradition" of Star Wars going forward, although with JJ on board, I kinda doubt that's gonna happen. JJ just doesn't strike me as the kidn of guy who has the vision necessary to pull off such a changed approach, and is much, much more comfortable basically doing what George Lucas did, only "Faster. More intense."
