"I hope you are not trying to say that you would be happy with a world of Dragonlance that has the look and feel of the animation talents of the Real Ghost Busters. Cause then we really will never see eye to eye."
He directed a lot of quality american cartoons in the 80's and 90's. These are cartoon shows with a fairly low budget, designed by and large to sell toys, and not done by top-notch animators. Despite all those limitations, he made a lot of really good cartoons. I would go as far as saying he has a better pedigree of successful animated shows than anyone else in America. That's huge. (And I can say this because I'm a huge cartoon geek and have seen like, almost every cartoon ever.

)
I mean, he made Captain Planet into a big success, despite the show being, frankly, about the hokiest, lamest idea for a show that I can think of. He made the X-men cartoon, which was the first comic-book superhero cartoon that was good enough to really take off and attract fans. The X-men cartoon was so popular it had it's own matching comic book line devoted to it for a long time. You started seeing lots and lots of licensed superhero cartoons appearing because of the success of this show, even today.
He made Exo-squad, which was a show about a couple of lamo robo-suit toys that never really sold, and made it into a suprisingly realistic (For a childrens cartoon) show about war that involved mature themes and a whole lot of dying. Exo-squad was awesome.
Some of the complaints I can see, but the choice of Director, honestly, is one of the single biggest points in favor of the movie. They chose a really talented guy.
As far as the animation goes, we'll have to wait and see what the style will be. But in terms of quality, keep in mind that the clips on Toonz's websites are for, by-and-large, low budget UK childrens shows. It's indicative of what they can do in a short time for reasonable cost. For a Feature-length animated movie, the quality of animation is obviously going to be much higher.
I'm suprised so many people have trouble with this idea. Even in Japan, feature movies and direct to video releases have much higher quality animation than t.v. shows, even when we're talking about the same studio working on the same series. That's just a natural benefit of a higher-budget and lower volume, not that inferior animators are somehow used for television series.
Also, you can't get any style notes from the animators main site, we'll have to wait and see for movie images. Toonz is going to do the grunt animation work, not the concept art. All we know about the style at this stage is that it will be a mix of 2d and 3d, Kunoichi had a hand in producing the concept art, (Their speciality is refining character design, judging from their site) that Weiss and Hickman and even Wizards had a hand in approving the art, and that Weiss and Hickman apparently think it looks pretty cool. We'll see.
