In short, what the creators should have done is:

1. Dial it down with all the racism. There's hardly a scene where it is not black this and white that.

2. Less politics would have been most welcome 3. It would have truly worked much better as a two-hour-and-a-half movie instead of just filler scenes.

Unfortunately, it never lived up to its potential. Fingers crossed that they won't repeat these mistakes again.
