"If you want to see some action...
got to be the center
OF A TRAK SHUN"
My god, the first time I heard this I laughed so hard. It was kind of a badass moment for Ichigo, and this song was just so out there. I later found out (after I stopped watching) that the same guy who's in charge of Bleach's soundtrack also did Evangelion's.
Funny how you mention Ichigo's similarity to Yu Yu Yusuke. It never really crossed my mind before, but Bleach is *a lot* like Yu Yu Hakusho.
Gintama is awesome. Yes.
You might want to check out Soul Eater too, it's a similarly targeted show, but it's been pre-set for 51 episodes so you can expect things to be pretty tight. The production value of the average Soul Eater episode is much higher than you would find in an average Naruto or Bleach episode--something to be expected for a show with a designated time frame and veteran staff. If you liked Full Metal Alchemist, a lot of the creative forces behind that show are making Soul Eater. Check it out.
