Calm down guys, it's all speculation at this point. Movies VERY OFTEN get reshoots. The final draft of the movie wasn't even finished when they started filming. It probably just needed a little balancing out. It's still supposed to be a war movie, but it has to also be grounded in the Star Wars universe. (I just hope the rumored bad-a$$ Vader war scene remains)
At least the director is still on board. When director Richard Donner was fired from Superman II, they lost something. Watching the darker "Donner Cut" didn't actually make it 100% better though. The studio had a point. If they would have worked together on the problem, they would have made it epic! Instead they shot almost the whole movie over without him and ended up with a mediocre sequel. Just food for thought. Again, I'm glad the director is still on board.
