1. dragon ball
2.reboot
3.gurren lagann or dragon ball GT
1. DBZ or Reboot (both make me nostalgia all over the place
2. Gundam
3. Not sure ATM.
Why all the hate for ReBoot?!?!? I'll admit that the earlier episodes were cheesy, but past season II, the show takes on a form that is incredible for it's genre, and it was years before it's time in computer references, I still get giggly when I hear names like Hexadecimal, SCSI ("Scuzzy"), Dot Matrix, Megabyte 
1. DB/DBZ (All Hail the Legend)
2. Sailor Moon
3. None right now, line up is almost perfect.
1. Cowboy Bebop/Batman/Cartoon Cartoon Fridays/DB/Everything not in disliked
2. Sailor Moon/Tenchi/Beast Wars
3. Venture Bros./More Sunday Movies
1. Gundam Wing/Kenshin - 2. Cow and Chicken - 3. Code Geass/Char's Counterattack Movie
1. Cowboy Bebop / Samurai Jack / Batman: TAS
2. Reboot / Beast Wars
3. FMA: Brotherhood / Samurai Champloo / Ghost in the Shell :S.A.C.
For my #3, I think those three shows are essential adds. Any one of them would add something really solid to the lineup that adds very watchable episodes the whole way through each series. Seriously though, Champloo and Brotherhood are just so damn solid; in truth, you'd think their addition is only a matter of time.
1. Gundam Wing
2. Spaceghost: Coast to Coast
3. Zach Bell, Prince of Tennis, Naruto, FMA Brotherhood, or any anime that was shown on Toonami at any point in time
