I'm with Jayson... This felt like just another boring episode trying to be its own "thing" and not very much part of a greater story. It almost felt like anything of the greater story was actually shoe-horned in, at best. Very meh, again.
I liked some aspects of it, but this is kind of what bores me about Rebels, and stuff like this bored me in TCW too when it crept into the show.
But like Jeff's said, if you're wanting Landing at Point Rain every week, Rebels will always disappoint you. I just feel like the premiere was vastly superior, and they should stick with the "war" in Star Wars and give us battles, space combat, missions, etc.
Going and finding the Clones fishing for a giant worm, just so you can get your Jaws homage on, is the kind of stuff that makes me dislike Filloni's directing. He sometimes goes too far with that stuff and makes it a focus.
Regarding the Clones, TCW explained all that jazz about why they turned... In general they'd not be loyal at all if not for the programming, or they'd at the very least be more independent all around. The 501st may be important to the Empire, but in TCW the 501st was no more or less loyal than any other Clone legion really. They just happened to be Skywalker's personal Legion... and so remained afterwards I guess, and those may have more of a loyalty/fanaticism to them I guess.
I'm digging the pre-AT-ATs next week since we got early glimpses of them, but 3 AT-ATs vs a derelict AT-TE seems mismatched to me.
I will say I like them playing up Kanan's mistrust of Clones... even if they used the mistrust angle stupidly with Wolffe's actions (totally agreed, that was beyond stupid even for a half hour show). It makes sense, but it feels like they'll pretty much drop it after this episode too. Everything's just AOK now.
It's a kid's show much more than TCW was, so it is what it is. I always find some stuff I dig about any given episode. Kind of want to compare interior shots of the AT-TE to the ICS of the AT-TE. Didn't see it jiving completely there.
