Maybe for once he wanted to leave a show before it was pulled out from under him?
Okay, this had some merits and some potential. The story was okay, although I still find it odd that they're focusing on such peripheral characters when it would be so much more interesting to follow characters like Bail Organa and Leia, Vader and Tarkin.
There were some parts of the design work I liked, such as the propaganda posters and grafitti in the town on Lothal (?). But a lot of the time, I found myself thinking, "This would look so much better in 2D animation." The textures on the characters are way too smooth and plastic, which is especially problematical for anything involving hair. I could hardly watch Ezra because of those rubbery blue pseudopods on his head that writhed around with minds of their own, looking more like some kind of alien starfish parasite feeding on his brain than anything resembling hair. Just a really, really bad character design, at least for 3D. (And why was Obi-Wan so babyfaced?)
I wasn't crazy about the overly mobile and bouncy character animation either. It was kind of jarring in the scene where Kanan explained the Force to Ezra -- Prinze's voice was this solemn monotone, but Kanan was animated as moving around in a very lively fashion that clashed with it completely. The animation on the free-fall sequence in the corridor was reasonably good, though -- although they made the perennial mistake of showing people "swimming" through air, which doesn't work since air is a lot less dense than water. The most they could do is rotate around their centers of mass, not really propel themselves forward significantly.
I also didn't think much of the music, which apparently is still by Kevin Kiner. I often wished he'd use more of Williams's themes in The Clone Wars, but this is a "be careful what you wish for" situation, because now he's doing nothing but variations and pastiches on Williams motifs, and it feels very derivative and lazy. And it's often off-putting when a familiar theme is used for the wrong thing, like when Obi-Wan's leitmotif was heard in the dogfight sequence or when "Leia's Theme" from ANH was used for the Wookiee family's reunion. Not to mention that cue I've heard in one or two of the previews/shorts that's a pastiche of the basket chase music from Raiders of the Lost Ark, which isn't even in the right universe! It's way, way too imitative and unoriginal. I wouldn't mind hearing familiar themes used when they're appropriate, like Obi-Wan's theme for his Holocron message or the Imperial March for the Empire or Vader (although I still find it odd when that motif is used in anything set before TESB), but there should be more original themes for original characters and situations.
So I'm interested enough to keep watching, but there's a lot about the execution that I don't like.
I totally agree with you about the music. I know they're going for the original trilogy there and I understand it but it came across as overkill and unoriginal. Just like Kanan's wooden explanation of the Force, copying that from Obi-Wan in the original trilogy and adding absolutely nothing new. Embrace the nostalgia but don't revel in it, which is what I felt like the pilot did too often.
