I've only watched a little bit of it and plan on watching more of it when I have time. However, I can safely say that the orginal YuGi-Oh was MUCH better than this follow up series, YuGi-Oh GX.
Either that or I'm just attached to the original .^_^.
Either way, the animation is different...I don't know. Like I said, maybe I'm just used to the orginal, but the plots are DEFINITELY better in the original.
I'm not saying GX is bad though
