Shame they could not fix the uneven nonsensical script and sloppy characterisation.
The thing about this system is that it really only saves on money and time for the studio. It doesn't primarily up technical barriers but rather monetary ones. Instead of having to render a frame in multiple passes, they can use the new system to do it faster which means it costs less and cost is king in movies. It's essentially down to making a factory line more efficient.
So for example when they pitched the mini bots. (Tiny bots that form up shapes kinda like the sandman in spiderman.) It originally would have been. "We can do these shots for $x million" which may have been too expensive and not enough bang for the buck. Now with this new system they can do it for less and make it look better because the system is better. So it's less a case of the art is better or design is better. But rather, the tools are better. It opens things up for the artists, but I would argue that does not equal better movies. Toy Story 1 is an incredibly basic movie by todays standards and it is still a classic, full of expressive, well written and designed characters. What makes movies good, are good movies.
Big budget animation is like big budget movies. You can have more complexity and effects. But if the script and aesthetics are not up to muster then it's not going to be a good movie. (Which I gotta say, I think is true here.)
