Rogue One focused on a group of new, unknown characters and grossed over $1 billion.
Except "Rogue One" (RO) did it first, and while the franchise was still on a fresh and high note. This would be the first standalone/tie-in, which would have people understandably interested. And on a safe issue (the death star, everybody loves that big logo in space). And all based on a minute's worth of dialogue and 30 second text crawl. For 2 hours. Doesn't matter if it's got a fitting look to it, it looks seamless but does it
feel seamless? The characters were all cardboard, save for Tarkin and he's sadly used the least. Leia doesn't blink at all so she looks even more scary as a result. The story"telling" hopscotched around planets more abruptly than anything else ever made. Even worse than any of my posts. Official continuity got ignored despite this type of story needing to adhere to official continuity because the story it's referencing takes place shortly later (facepalm). Vader's moment of glory looks great but sticks out badly compared to "A New Hope". Or was Vader merely half-asleep in episodes IV-VI to make up for all the Force power he used in RO? (Er, I hope not!)
What's Fett going to do? How will audiences, casual or otherwise, be intrigued and entertained for 2 hours as he roams around the galaxy capturing good guys for the Empire? Or is his origin going to actually do something big and do what "Solo" should have done and start Boba off as a decent chap but has an epiphany or something? Will it make Fett's ultimate death, falling into a Sarlack pit with the pit belching for lame comedy relief afterward, be any less bland? (Forgive me, but Kennedy didn't kill Star Wars. If it didn't die in 1983, the 1997 special edition killed it. Then came the prequels *shudder*... Ever since then, all people wanted was something mindless that felt good. TFA was effectively perfect in that regard.)
And it could be worse: What if "Fett" takes place
after "Return of the Jedi"? He's upchucked out of Sarlack's pit due to indigestion (or ends up out of the other side, eww) and because they brought back the comedy team ousted from "Solo" since Boba deserved a comedy outing whereas Solo needed to be serious. Or might that be better, a Fett Sequel over a Boba Prequel? Either way, without any vision or point, 2 hours of Fett wandering around will make people long for the 1978 holiday special instead... or, worse, the Donny *& Marie skit... (*shudder* 1978 hair and beard styles *shudder* )
