First of all: I loved TFA, even though plot-wise it was far from perfect. I think most of my problems are related to the Starkiller. Why would they create an elaborate superweapon that can only fire twice? So what if it was just about to be completed and only needed to swallow the sun to become fully operational? That way we could cut the destruction of Hosnian Prime (aka the planet we’ve never seen before and now it’s gone). The backstory would probably require some changing to give the new Republic a reason to declare war, but we’d have to wait for the sequels to see where the plot is going before doing such a change…
