So, Season 2 premiered a few weeks ago on Boomerang. As usual, the network hasn't done any sort of promotion or advertisements for it. Strange how the network seems to have a vendetta against one of its own programs..
Last week's episode, "Alone Again, Unnaturally" was definitely one of the best in the whole series. References to Blast Processing, Sonic getting pulverized, and Eggman freaking out thinking his lair was haunted.
Sonic Comic writers Ian Flynn and Evan Stanley are confirmed to be writing episodes for this season. Executive Producer Bill Frieberger has hinted at 2-part episodes, and has said more characters from the games will be appearing this season, including the return of Shadow.
Sadly, the show likely won't be renewed for a 3rd Season. Since the move to Boomerang, ratings have taken a massive hit. The Boom brand will likely die off after the end of this season.
For those without Boomerang, new episodes will reair Saturday mornings @6am on Cartoon Network.
