We don't miss Toonami (yes we do), we miss the kind of anime it used to play. Shit like Yu Yu Hakusho, the heavily edited Tenchi Muyo, Cowboy Bebop, etc. were all made for little boys wanting to watch something more grown up. In the middle of the day, you could watch someone get fucking shot to death on Cartoon Network... But how many still running animes are like that today? The only one I personally know of with that same kind of spirit is Fullmetal Alchemist: Brotherhood, and it just ended last year. But then, even if a new one did come out, how many of you would watch it at like 4 in the afternoon every day after school? For everyone who WATCHED Toonami and isn't just lying to be one of the cool kids, you've got to be like 18-25. Your days of regular TV watching are fucking over. So if one of those animes come out, you're either going to DVR it on another station or you're going to download it. Toonami won't magically bring it all back.
And as far as I'm concerned, if it isn't Robot Chicken, Venture Bros, Metalocalypse, or Aqua Teen Hunger Force, it isn't Adult Swim. The rest is just asshattery (specifically if it's live action).
