Most of those examples are dreadful. The final one at least doesn't look like cheap department store mannequins. Other than that, there's a ton of 3D porn on the Internet made by amateurs using Poser that's better on a technical level.
CBS/Paramount can easily go on without "success" on the scale that these examples represent, although it's easy to imagine them hankering after the Clone Wars
Let me spell it out: if a studio is going to do 3D animation they ought to do it well. The examples you keep throwing out as "gotchas!" are poor examples of 3D animation and utterly fail to make your point.
