If you have the same director (and probably writers too) then I think it's gonna be more like a prequel than reboot.
And for anything I hope? I donno. As the movies went on, the dumb stuff got (mostly) dumber, so I hope there won't be some "Jar Jar" like character in the 4th installment. I just want something as decent as DOTM, but with pacing that's more even than DOTM.
