That's really no excuse in my book. Good entertainment is recognisable no matter what age group it's directed at. It's like when people defend something by saying it's "just a dumb action" but there's absolutely such a thing as a good dumb action movie and a bad one. I watched the 2 minute clip of the show and and wanted to brain myself I was that bored but I could happily go watch multiple episodes of the old Sonic The Hedgehog cartoon because it's actually a decently written, well paced show. Today's generation is the one growing up on smart sharp shows like Adventure Time, Gravity Falls and MLP:FiM, I'm struggling to imagine which kid is going to retain a show like Sonic Boom with any of those shows being broadcast anywhere near it.
Also the constant quips in the game clip made we want to go put my fist through something innocent and undeserving. I have no particular affinity for Sonic but this whole project looks like a wretched disappointment after Colours & Generations actually turned out to be decent games.
