This series so far is decent but it's suffering from a few issues. Some with casting, some with directing.
Hera's character is unbelievable - mixed with poor acting and too much makeup, she's like a pretty girl stuffed in a Star Wars outfit with cute but out of place expressions. Conversely all of the villains here are fantastic, especially Shin (the Ukrainian actress). Just a fantastic expressive performance. Very believable.
The overall problem I've found with this series is pacing, Ahsoka's character suffers at times due to her vacillating between a lethargic smug sage to a top fighting Jedi. The directing is also suffering from music overload. Intense music being overlaid on battle scenes and light saber fights is actually smothering the flow of the scenes. If you notice the music more than you notice the action then you've probably got too much music.
All that being said, this is probably my second favorite series behind The Mandalorian. I'm still holding out hope for this one to get better though as the villains are exceptional.
