I say it looks OK for Rudolf, but it meshes horribly with Pokemon and DQ because both prominently feature human characters who just don't work in that style. IIRC the same studio that worked on these films also worked on the 3DCG Doraemon film a while back, and it looked atrocious.
Haven't seen the film, but neither OLM nor Sprite worked on
Stand By Me, it was Shin-Ei Animation and Shirogumi (Robot Communications might've just been a producer and not production, but I dunno). It looks nice for
Rudolf not just because of more original models, but because of the CGI director, Motonori Sakakibara, the same man behind
Final Fantasy: Spirits Within, which visually still holds up nicely and still is historic to animation. Some people have said the look of the human characters grew on them since it's better seeing them in motion than in still-shots, but yeah, they do still look a little off. They could've toned down the eyes, or even fixed the noses, but from what I can tell, everything is otherwise spot-on. The
gorgeous backgrounds in general I think is testament to how far CGI has come, and that Japanese animation
does have a future in CGI, but there needs to be reformation in the workforce in order for that to become much more commonplace. Otherwise, animation studios will just continue to outsource to places like Korea for that Nickelodeon-tier CGI, and that's the most-likely outcome.
Also, the Japanese filming industry is dead. I don't believe for a second those stiffs in suits would greenlight a budget for better CGI.
Sure, I'll take your word for it, but I think studios like Sola Digital Arts, Digital Frontier and Marza Animation Planet are our future for
good CGI anime films. Although Toei can make really nice-looking CGi films if
Captain Herlock is anything to go by, but that may have been thanks to Marza.
