Random thoughts:
Biggest surprise of the episode: seeing a semi-plausible explanation for the turtles' transformation into data--with a continuity nod, to boot. After all, if the trascendental lathe (that machine that the turtles used to make their weapons in Fast Forward) can transform data into matter, then it's not a stretch to think that it can be modified to the opposite. Plus, it explains how Donny's been able to make the turtles' new toys in a short amount of time. Very efficient detail, from a writing standpoint.
Speaking of efficiency, I also like how the Cyber-Shredder's opening story can be used to justify the Shredder surviving the TCRI explosion in Secret Origins...he didn't. While the plot development leaves a pretty obvious question of why Karai didn't simply clone the little bug back to life after he'd been banished, that will, I hope, be explained later.
I'm still of two minds as to the series' blatant use of previous seasons' footage. It's a blatant money-saving method, of course, and not done subtly at all, and yet I can't help but finding their use of the tactic gutsy. And charming. And reminiscent of the unprofessional vibe of the original comics.
While I'm not enamored of the turtles' cybernaut outfits, I do like the rest of the cyber aesthetic. Original it may not be, but it looks coherent and "fitting". While I don't think the concept has much strengh for more than a handful of episodes--particularly since it's a variation of a concept the series has already used twice--I don't mind it here.
This episode and the last were both written by Mike Ryan, who penned some of the best TMNT episodes and was, I believe, one of the main series' writers. He'd been missing for the past season or two, so I'm glad to see him back.
So far, I'm liking this season quite a bit--better than both seasons 5 and 6, at any rate. Given how nervous I was about it, I am very glad that I can say that.
