Don't be ridiculous, it's just a remake of ESB...
I'm sure we'll hit some of the highlights of ESB in this. Disney is keenly aware that nostalgia pays dividends for its Star Wars films. But I think they've also realized that a fresh take on things is paying off as well.
TFA was not just a remake of ANH. Yes, in broad strokes/high-level plot points, it was. It hit many familiar beats. But it also did a bunch of stuff differently. It has a more varied cast in terms of demographics. Its emotion, I would argue, is much more raw and intense. When Han dies, it's an incredibly intense scene across the board. The acting, the music, even the lighting is all really intense. Way moreso than Obi-Wan's duel with Vader, which takes the mentor figure out of the film and spurs the hero to action. The space battle to destroy Starkiller Base is visually intense as well. It's literally sucking a sun dry, with night descending on the world itself, plunging everything into darkness, all while the Resistance fights to stop them. Again, way more intense than the Trench Run from ANH, which is, visually speaking, actually a pretty brightly lit affair. I'd argue that the tone is in many ways more somber, too. Yes, the good guys won this round, but it came at great cost, and everyone knows the stakes have just gotten incredibly high. It's a victory, but a melancholy one. Far more mystery is introduced in the film, too. ANH was pretty up front with what was going on. The Force wasn't a big mystery. It was exactly what Ben said it was, and the audience had no reason to assume otherwise. It's only after additional films came out that the Force became a bit more mysterious. Luke's family history was unknown to Luke and to the audience, but for the most part, it didn't really matter. Again, there was no reason to doubt Ben, so it didn't come across as actually generating a mystery to be uncovered.
Some may disagree with some of the differences between TFA and ANH (e.g., if you, like me, are not a fan of "mystery box" contrivances, you may not like the introduction of these big questions that have yet to be paid off), but the film is still different.
Rogue One, likewise, was a
very different Star Wars film. Yes, it's set in a very familiar setting and focuses on an event where we already know the general outcome (theft of the Death Star plans). But it's tonally way, way darker than pretty much anything that came before. The Star Wars Wild Bunch, really (although, they're more heroic than the Peckinpah film's characters). The rebels are cast in much more morally grey terms, too, with Alliance Intelligence appearing willing to really get dirty to complete the mission and the one insurgent group on Jedha actively engaging in torture. And, sure, it featured a bunch of sequences that hit emotional beats similar to the other films (a big starfighter attack on a space station, a ground battle against big walking machines, heroes shooting their way through Imperial corridors), but the overall path that the movie follows is different from any Star Wars movie that came before.
I think Disney has recognized the success of these films, and recognized that taking things in a different direction -- while retaining surface-level familiarity -- is paying off. So, while there may be rumors of this or that plot point being hit that mirrors an older film, I think it's a safe bet that whatever comes won't just be some tired retread of the same ol' same ol'. Although I've admittedly kept myself in a near total blackout about the new film. (And would appreciate staying that way, so any details, please spoiler-tag in here, if you wouldn't mind.)
Honestly, the only thing I've been worried about with Disney's current stewardship of Star Wars is the apparent interest in mining old characters for stories. I'm less interested in [Character]: The Backstory, and more interested in new characters. Had Rogue One ended differently, I'd have enjoyed seeing what happened next for that group. Assuming this new Han Solo movie isn't a complete disaster and I like the characters that are introduced (and hopefully not killed off), I'll likely enjoy the Solo film being the platform from which
their stories are launched, rather than creating a Han Solo franchise. (I have the Brian Daley trilogy for that, if I want it.)
