Eh, Toonami got me into a lot of anime like Yu-Yu-Hakusho/Cowboy Bebop/ and mostly Rurouni Kenshin.
Back when DBZ was on after school was awesome, especially back to back episodes since tv in that time slot sucked ass by comparison. DBZ isn't the greatest show ever, but it was/is enjoyable to watch at least. These days Toonami is shit besides running One Piece (meh, I watch Fansubs, but still the new english voices are much better than 4Kids, so i watch just for them) and... i don't even know what else they air.
CN in general is going down slowly, and has been for a while. No more Futurama is mehhhh. They're turning into Fox 2.0 with airing Family Guy and American Dad. Both shows really don't do it for me anymore. Once in a while Family Guy is alright, but American Dad is never funny. I guess I don't have the right mentality to enjoy these 15 minute shitty animated shows that they love to air. They're not funny, they just try to be edgy and COOL instead of being well written or have decent jokes. They go for shock value these days, which is pitiful, really. I blame that with the rise in popularity of Family Guy and Aqua Teen Hunger Force, but meh.
These days I find myself clicking to CN, seeing a shitty show on, and wandering over to Comedy Central. Soon new Futurama will be airing there, and in addition they still have South Park and actually funny things on there.
My best advice for Toonami... don't watch it. If you want to watch anime, go buy the dvds, because anime like Cowboy Bebop/DBZ/Trigun/Rurouni Kenshin are watchable no matter what.
