I bloody hope not. They should have left it at three.
I found the pandering for Rogue One:
Remember this character? OOOOOOOOOOOH! from the audience
Remember that character? OOOOOOOOOOOH! from the audience
Remember these characters? OOOOOOOOOOOH! from the audience
That was the weakest part of that mostly decent and watchable prequel.
This trilogy would only exist to do anything but ... perform that unnecessary feeding of eager sentimentality eaters. Finding age appropriate actors to fit in between that trilogy and the current one? Is going to be a herculean (and unsatisfying) task.
