The world building is good. Isn't trying to out-do what's been done, fits in pretty good. It was a given they weren't going to leave the kid off so the story was just a vehicle towards the bigger story. Thrawn had to be part of it, this was as good a way to bring him in. For me it was a misstep giving the kid a name, particular such a harsh one. Nor should they have tried to establish a father-son relationship that I enjoyed better as an older and annoying younger (who might actually be older ) brother. After all, the Mandalorian is really in the same boat as the kid. He's never been trained.
Dawson: Her stature and attempts to mimic a voice made her pretty much a different character given Tano's name. Not terrible. Not great. Certainly lacking charisma and wasn't particularly compelling. Her body acting so-so. Not sure if Eckstein could have pulled off the latter she would have been worlds better in the former. Ahsoka has already been established as older-wiser, this was not new. An older actress was a must. Dawson works as a one-off celebrity visit that could have been filled with many equally but would have been annoying or at least something to get used to if she'd become a regular.
Not as weak as the first two but not as strong as CH 11 and 12.
