I do wonder about that: it was also criticized for its jarring 3D effects (arguably, some of it due to artistic choices, but clearly not all of it), to the point where it was hot-fixed while it was still shown in theaters. So it might not be the advertising you might want for Blender.

But it might also be the consequence of its flawed production process.

Blender was used for other big films as well. But it is still not an industry standard. But that might change very soon.
