Lack of quality in the details yes but the fact that characters and scenes depict consistent and real movement and evolution as opposed to the cinemagraph and frame morphing stuff we have had so far is still remarkable!

It has a comedy like quality lol

But all to be said, it is no less impressive after this new demo

There are absolutely example videos on their website which have worse quality than that.

Depends on the quality of the prompts.

Drastic difference in quality of the prompts too. Ones used in the OP are quite detailed ones mostly.

That particular example seems to have more a "cheap 3d" style to it but the actual synthesis seems on par with the examples. If the prompt had specified a different style it'd have that style instead. This kind of generation isn't like actual animating, "cheap 3d" style and "realistic cinematic" style take roughly the same amount of work to look right.
