Sadly, it seems the bloom's already off the rose for this CGI entry, as CN has slotted it in a double-play block on Sunday mornings at 6 am (ET), hardly a prime spot. The fact that it is, at its core, an action cartoon, moreso than a comedy-adventure show, works against it. Still, the CGI animation works better for Sonic, whose roots, of course, are in video games, than the Japanese anime of his last series, Sonic X.
Some new characters have been added, including Stix, a badger, but those who remember the first series from the 90's will be slightly disappointed to see that Sonic's old sweetie, Princess Sally Acorn, is not around. In fact, there are two schools of thought, if you go by message boards, in regards to Sally, as it seems the mallet-wielding Amy Rose is Sonic's current love. I've been out of the loop with Sonic for so long, so you'll excuse my ignorance.
Anyway, let's scope out the opener:
Dr. Eggman, nee Robotnik, hasn't changed. For a guy with a genius IQ, he's still a loser.
