Gracious me, what a disgusting way for Maul to go. Not only does it flagrantly ignore lore precedent from GL, it also runs as counter to the character as anything I can think of.
First of all, we know from TCW that even as half the man he used to be, Maul was superior
to Savage and an equal
to Obi in his prime. The same Savage who held his own
against Dooku. The same Obi prime who defeated
the Chosen One.
Both Obi and Maul had grown old living in desolation for a long time on their respective worlds, with an according decline
in fighting prowess. So where the hell does Dave get off thinking the gap between them would have grown so great?! And that with basis in real life swordsmanship? For blood's sake, Dave! SW doesn't care about reality! Virtually every lightsaber duel in the movies was a meeting of masters, and they didn't operate by this logic!
Lore aside, it royally failed from a dramatic perspective too. Maul is as far as you can come from a nameless redshirt, and his treatment in that "duel" only has precedent from those. SW logic on this is simple: Only nameless, faceless characters get one-shotted without extenuating circumstances in play. And Maul has forever been one of the most powerful characters in SW, even among the named, faced ones.
Worse, consider the damn character! Maul's only use by GL in the movies was as a lightsaber duelist. His entire character concept was "scary dude and poster-boy for PT-style flashy lightsaber duels". To let him meet his end without coming full circle on that is the height of disrespect for everything he was. It's as if Thrawn died getting outwitted tactically by kid Ahsoka.
It didn't even do anything for Obi-Wan. Obi didn't get to finish what he started, which was overcome a terrifying lightsaber duelist. Instead he got to easily cut down some punk. Even the Visionaries comic the thing was based on knew to make RoboMaul powerful enough Owen had to act as tiebreaker.
As for the Season Finale, it felt underwhelming compared to Season 2. But then again, Season 2's was some of the best SW I've seen in my life. Had really hoped for some payoff on Ezra's slip to the dark side from seeing someone on the crew die, but instead we only got Sato and maybe Bendu.
Speaking of Bendu, if anyone can see these episodes and still think his words on the nature of the Force don't carry greater weight than some random Force master, then they are beyond my ability to convice. The guy is straight up primordial Force of nature, up there with Yoda, Father and the Priestesses.
