No one is saying its going to be a flop (money wise), people are saying its not the best idea. For example, I don't care if its Disney or Universal or Paramount, etc
(although Disney has a bad track record of SEQUELS of non kid films) who has the rights to SW, I don't want to see another movie. It happens time after time companies just keep bringing out new films of old classics and the majority of the time they never live up to their name. Also there is no need for more sequels, there are no questions that need to be answered, there is no need. The only reason they do this kind of thing is money. It would be a similar situation if Universal made a new BTTF movie, there is just no need for it.
Although when it comes to the park I doubt HS will get anything, I see DL getting something but not the WDW property.
