Am finally getting caught up on this season's episodes. I can't believe how brutal this episode was (genocide, torture, sadism) as well as the past two and the Umbaran ones. If I had young kids I certainly wouldn't let them watch this show any more without previewing each episode ahead of time.
As for the plot, it was decent, but had some holes, such as what happened to the rest of the slaves from other species in that facility at the end, and why the Republic felt the need to shoot missiles at it to accelerate its collapse, with potentially many unaccounted for slaves on board. Were those ALL the Togruta people left?? Have fun repopulating a whole planet with like 20 people. Seems to me The Republic should get on with invading Zygerria given how many Republic citizens must be held against their will there (remember the US used British internment of US sailors as justification for starting the War of 1812). Though I guess Palpatine protects the planet politically because he needs the slaves once he takes over.
P.S. Since the violence and dark themes already pushed this episode arc way over the top, they should have gone all the way and properly duplicated Ahsoka's slave outfit from the comics this arc was based on.
