I know what you mean. The animation may look like a good improvement, but there are a lot of storylines that they could take. Personally, I also would have loved it if that episode where the monsters came to Earth was not a dream. There was just so much that they could have used for that. While it is there to sell the game, there isn't anything wrong with Chaotic from actually having a season plot/storyline to go with.
Wait a second. Chaotic is at number two now? So that would mean that Yu-Gi-Oh! is at number three. Wow. I didn't think that the card game would be that popular. I guess some people seem to find it interesting, even though the way it is on the show never really interested me. In fact, from the episodes I've seen, the ones where they're exploring the world of Perrim are more interesting than the ones where they're just playing the card game. But that's just me. You also bring up a good point about how the season ended with a cliffhanger so hopefully that will lead to a seasonal plot.
