It's a very clear difference between a cheap animation and Ghibli. Anyone can see it.
In the first case, there's only one static image for an entire scene, scrolled and zoomed, and if they feel generous, there would be an overlay with another static image that slides over the first at a constant speed and direction. It feels dead.
In the second case, each frame is different. There's chaotic motions such as wind and there's character movement with a purpose, even in the background, there's always something happening in the animation, there's life.
