for gonzo : there are about 100 good eps after 26 of naruto... maybe give it another chance.

for gonzo and others :

Outlaw Star (subbed of course... dub if you like it)
Inuyasha
Full Metal Alchemist (if you haven't seen this, you need to. One of the best series' ever)
Gundam Wing (so good)

I wont recommend anymore at this time.
