Finally got to check it out, and so far, I quite enjoy it. I'd say it's probably my third favorite Sonic cartoon behind SatAM and Adventures. A definate improvement over Sonic X, which I did like but too much Japanese kiddy show stuff seeped in (the reason behind Chris being on the show, as the audience surrogate character). I especially like that, without Japanese influence, Amy isn't all Japanese housewifey to Sonic and she manages to be a wacky character in her own right.
Seems that they've slightly Simon Belmonted Knuckles, which I gotta admit I don't mind specifically for this show. I like them being slightly friendly rivals instead of Knuckles being all broody and Protoman like. Love his new ego boost. And Sticks manages to be a solid character so far.
But of course, I must talk about Dr. Eggman. I'm loving Eggman as I usually am. They've managed to make him even more of a buffoon than before, and that's awesome. I've always preferred funny Robotniks over serious ones. The episode where he crashes on Sonic's couch was already a series highlight, and I love how his secret devious plan bit him on the butt hard. And I'm also happy Cubot and Orbot are in tow. Eggman always needs a couple goofy sidekicks to give that extra edge of humor. From Scratch and Grounder to Bocoe and Decoe. Glad to see those characters from the video games managed to keep their roles in the cartoon. Guess Cubot's voice chip has been repaired though. Would have been funny to keep his damaged chip a running gag, but it would have gotten old.
