Yeah, the new art style only works with still shots, but otherwise, everything else looks stiff and blocky.
Luckily, they're transitioning to a new art style with the Super movie that's more free-form, sketchy, and rounded. It looks far more fluid and natural, and they even manage to turn the dial back on "hard-edge" DBZ style occasionally.
And yeah, Jump Force looks really weird.
It's like someone saw those weird "Let's remake this retro game in Unreal 4" videos and said "Yeah, how about we put these anime characters in that plastic, photo-realistic art style!"
