That .000001% being the most knowledgeable and dedicated of the franchise's fans over the decades, who were excitedly posting about ROTJ back when the Internet was, not even in its infancy, but embryonic. And remember, you've got to throw in not just the novel readers, but the comic readers, the RPG and video game players, the cosplayers, the toy collectors. And thanks to the EU's efforts at making it all fit, there was a LOT of crossover between those media demographics. Alienate those fans at your own risk.
The number of those fans are a drop in the bucket. They really are. Studios aren't interested in a tiny number of fans--regardless of how rapid they might seem. They want as many butts in the seats.
And those fans, they aren't going to influence the vast majority of people.
In other words, they can still alienate those fans and still be just fine when it comes to the box office. Besides, even those alienated fans are still going to watch it at least once in the theater, just so they can tell their friends how much Disney raped their childhood.
And what/when was the last blockbuster hit movie Harrison Ford was in again...?
Well, I think it would be more fair to compare it to him returning to a franchise. So....
Crystal Skull in 2008 pulled in over 700 million dollars world wide. Not to shabby, actually. In fact it did better than
Captain America: Winter Soldier
But, then, are you suddenly arguing that these rabid Star Wars fans DON'T want Harrison Ford in a movie? Or that they don't care he's returning to his iconic role? You can't have it both ways.
At this point, the question isn't whether or not the new Trilogy will succeed, but by how much.
I, for one, wouldn't be too sure of that. Most of the moviegoing public may be only vaguely aware of
The Clone Wars too (they certainly didn't go to the movie theatres for its pilot) and thus don't know of the salvage job that show did on the Prequel Trilogy. So, using your logic, the last most people know of
Star Wars is
Revenge of the Sith - and the Blu-Ray that saw Darth Vader's most infamous line from that movie attached to
the pivotal moment of ROTJ. Yeahhhh. Nowhere to go but up from there, right?
Regardless of quality, the Star Wars prequels crushed at the box office. If the Star Wars brand could survive Episode I and II, and still allow Episode III to be a success...
And we agree, I don't think most people are aware of the Clone Wars cartoon. Like the comics, the books, cosplayers, etc.
The live action brand, I think is pretty safe. You have Ford, Hamill, and Fisher reprising their roles, you have a successful director with Abrams... They are going to have a very successful opening. Regardless of quality.
