I wish you would explain in detail how this new film looks unprofessional and what makes you qualified to judge what is or isn't professional? These are the top production values money can buy. Also a big drawing point to this movie is having the old cast back. I'm sure if they didn't have any cast members back there would be a lot of complaining about that too from other folks with opinions just as valid as yours. As Mark Hamill said, it's more about the new cast than it is them, they are there just to pass the torch. It makes sense to have them back.
