Because popular characters are not allowed to die anymore. That might invade the viewer's safe space.

What do you mean "now"? Obi-Wan, Yoda, and Anakin all turned into Force ghosts in the original trilogy. Basically, every Jedi that died in the original 3 films became a Force ghost. It's not until the prequels that George Lucas decided to put some limit on Force ghosts, that it was somehow a special skill to learn, instead of just something that happened to Light Side of the Force users.

Anyway, just finished season 2, already into season 3. The show is definitely stepping it up, and making the ties to The Clone Wars more explicit with Ahsoka and Rex. Having watched season 7 of The Clone Wars before this, even though Rex's comments are vague, they don't 100% line up with what they later depicted about Order 66 in that last season of The Clone Wars. It's close enough though. The tension between Kanan and Rex makes sense. I haven't seen The Bad Batch yet, so the number of "good clones" that didn't go murder spree on Jedi must be vanishingly small, so it's understandable Kanan would have issues trusting a clone after what he experienced. I thought Wolffe and Gregor would be featured more on the show, but after the initial two-parter, they disappear.

Introducing two more Inquisitors seemed like a way to not overuse Vader, which is probably smart. Vader wouldn't be as imposing if the team kept escaping him, like they do with the Inquisitors. I found it funny that the third Inquisitor in the finale never even took off his helmet before dying, like they didn't want to bother modeling a face for such a disposable character. Seventh Sister was the better of the two Inquisitors, but they're still not that competent. I did like the reveal that the Grand Inquisitor from the first season was a former Jedi. It seems like there's maybe two ways the Empire "makes" Inquisitors: from young force sensitives like the babies they were trying to kidnap, and from former Jedi that somehow didn't die from Order 66 and were later tracked down, caught, and possibly turned.

This season was good in juggling the whole crew, giving each an episode or two where they're the focus. I liked the episode where Hera encounters her father, and during one argument, Hera slips back into her "native" accent. Sabine has to deal with an old friend and then other Mandalorians, Zeb has an "Enemy Mine" episode with Kallus, and even Chopper gets an episode. It's a better balance than focusing on Ezra all the time.

The opener and finale episodes were the strongest. I was a bit confused about Maul, like is he supposed to have been moping outside the Sith Temple for years since The Clone Wars ended? It did add an interesting dynamic to Ezra, since it seems Kanan has not been warning him about the Dark Side of the Force, at least not well. Having Ezra tempted by the Dark Side opens up possibilities for season 3.
