Ok, I've watched so much anime...I'll tell you the series I liked the most:
-Ranma 1/2 I still watch it, as it's on TV here in Spain every afternoon (the daylight starts switching off aproximatly at 9:00pm in summer in Spain, so I'll consider 7:30pm is afternoon)
-Cowboy Beebop (such a nice series, the final chapter was amazing)
-InuYasha I liked this series a lot. I think this animation was really well drawn.
-Dr. Slump
-Dragon Ball The best anime ever done
The best anime cartoon are Dragon Ball, and the one who opposes me will become my enemy!
Dragon Ball was the first anime I watched, at the age of 6, and it impressed me so much I kept watching it 'till the series finished.
I could go on telling you about lots of anime series I've seen too. For example: Doraemon, Muscleman or Mazinger Z when I was a kid, and Yu-Yu Hakusho, Sakura the Card Captor, or Utena are some I've seen recently.
Although there're many I've watched too, but I can't remember their names.
As you see, I'm a great Otaku!!
