Toonami needs a new older skewing show. Something in the vein of Bebop or GITS. Shows with adults as the actual originally intended audience. Technically speaking Samurai 7 was such a show, but with it gone and another shounen taking its place, Toonami is in need of some balance. Next week's lineup is shounen, shounen, shounen, American/Japanese weeknight kids' show, American weeknight kids' show (that is strangely the most mature show on the block), shounen, shounen harem, shounen, seinen, seinen, shounen, shounen. And even that "seinen" had its two manga runs, for some reason, in a shoujo magazine.
Hopefully we get something along those lines when Thundercats ends.
