Usagi for 6- to 11-year-olds? That seems wrong... Part of the quirky appeal of Usagi is the way random characters die with that skull visualization. Hard to imagine a show for audiences that young showing much of that.
Did you forget what kind of very conditional TMNT fan I am? :) TMNT may not always necessarily be just for adults (teenagers can read it too), but it should never have been for little kids in the first place. I'm kind of a Mirage/IDW audience purist when it comes to that, and I on rare occasion get into works targeting younger audiences (like the 2012 TV series, at least for a little while) if it successfully overlaps with my interests.
But TMNT has its own decades-accumulated baggage when it comes to target audiences, reputation and brand recognition—I wouldn't necessarily say the same about Usagi, whose delvings into children's entertainment have been done far more sparingly over the years, managing to avoid most of the hyper-kiddification and kitschy merchandising that has befallen TMNT over that same time. So if Stan Sakai really thinks this new show is a good idea for his creation and he gives his stamp to it, then we can see where it goes.
What do you think?
