Let's ignore anime that have been on Adult Swim, for a moment, and focus on anime that are actually good (Besides BoBoBo-Bo Bo-BoBo, of course). Watch Kaiba, it's a 12-episode sci-fi anime, and it's deep. Really deep. You may get lost in it, it's so deep.
Naruto and Bleach are also terrible.
Bleach, IN MY OPINION, is very badass show. It's worth watching. Very epic element blending. You should watch a few episodes (like the first 20) and decide for yourself.
If you like Naruto, you'll love Bleach.
Oh, btw, my list wasn't THAT long...
Eyeshield 21. came out in 2005... Still addicted to it.
It's an anime about football which gets a lot better.... Please watch it
P.S. My favorite character: Hiruma Yoichi
Tell me what's urs.
Here's the link for the wiki... I advise you not to read it unless you want major spoiler alerts... But it just gives a list of the characters in general... Please watch and tell me what you think of it.
