I've had a weird idea. Since Japan seems to be willing to do anthology series based on Western franchises (Ani-Matrix, Batman Gotham Knights, Halo, Dante's Inferno), what Western series would you like to see Ani-matrix style? I'll start off with my dream project:
Dr Who -
Eleven Doctors, eleven stories, possibly with a common thread through each of them (Bring back the Black and White Guardians, maybe?), maybe even culminating in a multiple Doctor adventure. Doctors' number 4 (Tom Baker) on up are still around to lend their voices, as are most of the companions. Sound alikes could be used for Doctors' 1-3.
I've seen attempts by Americans to create anime-like Dr. Who fanart and even animation. But I want a studio like Madhouse to take a crack at it. Should be a lot better than the BBC animated Tennant adventures at least.
