What bothers me most about the show is the fact that it is something made strictly for those who watched Rebels.
The problem is that they had stated MULTIPLE times before the series aired that it was basically Rebels, Season 5. Watching Rebels beforehand is a requirement to understand what is happening in the show.
So it is kind of funny to me that people complain about that as a weak point for the show, the solution is easy… watch Rebels first. This show is a SEQUEL. Are you going to watch Jedi before Empire? Or Last Jedi before Force Awakens?
