the hideous klasky csupo designs look even more nightmarish in 3d. i get it. 3d is just better for costs and making back on those costs. but it adds another layer of ugliness to the show's already unpleasant art direction.
beyond that, this trailer is probably appealing to younger millennials who grew up with the show post-movie and remember it when the show was about saving dil in every episode, week after week.
klasky had wanted a show that was like the pilot and first season - a show about babies doing baby things and being cute. the writing staff saw it as an opportunity to be a little more clever with the setting and characters - and turned angelica into a villain who the babies would generally need to overcome in some fashion (through either her misunderstanding of the world or cruelly lying about the world). this didn't sit right with klasky, and after the first hiatus, that writing staff wasn't hired back. so the show became more in line with her visiion afterwards. it's just a lot of nothing. i'm expecting more of the same here.
