Toonami is awful.
There's HxH and the worst arc of JoJo, but those are essentially the only things worth watching there - reruns nit included, that is. And nearly everything, the aforementioned included, is readily available through legal means elsewhere without the Saturday in the middle of the night restriction.
The bulk of it is either stuff you could already watch or reruns of stuff aired countless times, albeit better than their typical Akame ga Kill premiere pickups.
And I get it, they had Samurai Jack which I've heard plenty of good things about and an upcoming FLCL sequel nobody asked for since it's wholly unnecessary. But does 2 or 3 original series of less than a dozen episodes a pop with erratic releases not even guaranteed to happen from year-to-year, much less seasonally, really justify staying up to 2 in the morning on a weekly basis to watch shows you could have watched on your own time?
