And yet, a C- effort at absolute best 

Cartoon Network has apparently decided to add googly eyes to all their shows for April 1st. If that goes for Jack too, I'm likely going to give it a pass until it's… not… that. Also, I know that I personally used to like to announce things on April 1st, but once again I've got nothing. It's not been a great past year as far as translation projects go, to put it exceedingly mildly.
Belated edit. It looks like Adult Swim is airing Rick and Morty's season 3 premiere all evening, and Jack is pre-empted to next week.

Impressions:

How easy it is to forget how obnoxious Kugimiya Rie nasally yapping is when you haven't heard it for a while. And how quickly one is reminded when she's voicing the 'cute' pet and won't shut the hell up while contributing absolutely nothing but the ongoing reminder that she's there. But anyway, there's something simply off about the production here, and I'm not sure I can fully put my finger on it. It's like the same kind of uncanny valley you get when mixing CGI and regular animation where things are moving at different frame rates, fluidity, and style, except that it's going on every time they animate anything more complicated than characters turning their heads. If I had to guess, they're probably using CG shortcuts in the action, in a similar way to Chain Chronicle, but they're either better at hiding it, or maybe just worse at syncing the regular animation to the forest backgrounds. Well, the dragons are obviously CGI, but the rest occasionally gets a little… iffy too. Or maybe I just got into some bad maple syrup. 

And the reason I spent probably a paragraph on "the animation feels kinda weird" is because the rest of it is just really bland and utterly uninspired. Nothing really attempted. No risks taken. All pointed edges sanded down to harmless fluff. It was already working from a hole by choosing Gran to be the protagonist instead of Djeeta, but it's just such a paint by numbers opening episode for a fantasy adventure. Girl flees evil empire, complete with masked, comically evil storm troopers, and comically evil, mustache-twirling villain, meets boy, he gets hurt protecting her, so she gives him magic dragon power. Not that there's anything wrong with not trying to invent the wheel with your story, but what I listed right there is also the sum total of the stakes they set down, as well as the character traits. They're all boring dullards; either simply petty evil, or have no thought expressed but "I want to protect the other protagonist." No quest is lain down, no particular big bad established, no hopes, no dreams, nada. If you only watched the last two to three minutes of this episode, you'd be completely caught up with… well… everything, so I can't help but wonder why they didn't just start from there and save us those 18 minutes.
