Unfortunately, some of the major themes from this week's episode have already been explored in the SW universe: chiefly, to swoop in and rescue a population from a fake attack is really Darth Sidious's plan to take over the Republic, in microcosm. I'm assuming that knowledge of that plan helped Darth Maul concoct his scheme this week. Unfortunately also, it was a foregone conclusion that Maul would win the duel. Were it not for its predictability and its not having much new thematic ground to cover, this would have been a better episode.
I guess what I'm saying is, in isolation it wasn't bad at all, but in the context of the whole series, it's really nothing special. That's kind of a bummer.
