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?
The problem there is Dave Filoni came out on several occasions whilst promoting Ahsoka and said the viewer didn’t need to watch previous content like The Clone Wars, Rebels or The Mandalorian to be able to watch or understand the Ahsoka series:

^ 'Filoni, who co-created the Ahsoka Tano character with Star Wars creator George Lucas, confirmed that Ahsoka won’t assume that audiences are familiar with Rebels in an interview with Collider. “I don’t think you would need to watch any [episodes of Rebels],” he said. “They’re all available on Disney+, so you can check them out there and that would be great, but… for me, if you really were interested in [Rebels] and if it got people that maybe don’t – aren’t as interested in animation into it, I would start [with], probably, like, maybe the episode, “Jedi Night,” where the sad thing happens to Kanan. Even if you didn’t understand what that was, it would propel you forward. If you just watch Season 4 [of Rebels], you’d be set [for Ahsoka].”
So “no”, Filoni stated the viewer didn’t need to watch previously released content.
From the 1st video from IGN, where Dave Filoni says: “I think it is important you can watch them of their own”.
NFBisms excellent post above also highlights some of the problems watching this series even despite being familiar with the previous content.
