This sums up most of the difference between Filoni (and current authors/past EU writers)... and Lucas.
George:
It's a movie for kids, it's a fun and entertaining modern-day fairy tale, the themes are surface-level and easy to grasp--
Filoni/others:
-- no! There needs to be a second and third layer to ALL of it! This is dark, gritty, mature, nuanced, for grown-ups!
George:
Ahsoka is a Padawan, she can handle this.
Filoni/others:
Ahsoka isn't just a Padawan, she's a child soldier in a warzone, because that's how corrupt the Jedi have become by joining the war and becoming warriors instead of peacekeepers! They'll use children as soldiers!
George:
Anakin falls to the Dark Side because his lack of discipline, caused his ambition to flourish, his emotions to run unchecked and his attachment to grow until it reached greedy levels.
Filoni/others:
Anakin turns to the dark side within days but it's actually a frustration that had been building for a decade, and when he kills the Jedi, it's because they've never really sided with him and slighted him constantly.
George:
Yoda's line about Jedi arrogance is a thinly veiled dig at Obi-Wan to intimate that the latter is being a bit too hard on Anakin because he can be arrogant too, somtimes.
Filoni/others:
Yoda's line about some of the wiser Jedi becoming arrogant is a commentary about how all Jedi have now become too political and have thus lost their way and lessened their connection to the Force.
George:
Qui-Gon, as a Jedi, is a bit of a rebel.
Filoni/others:
But actually, if you really think about it, Qui-Gon is the only Jedi who's ahead of the curb in terms of his understanding of the Force, and he's the father figure Anakin needed.
George:
The song is called "Duel of the Fates" because Obi-Wan is fated to have a similar duel with Anakin in the third film--
Filoni/others:
-- Nope! It's because the duel decides Anakin's fate because Qui-Gon is secretly the only guy who truly gets what loving without getting attached is about, and so when he dies, Anakin's fate is sealed because Obi-Wan could never measure up to becoming the father figure Anakin needed in his life.
