You miss the point. You really do.
The point is - some people can't be bothered to concentrate. Films aren't complex mumbo jumbo chaos that it requires super computers to understand - they just are stories which, leaves themselves to the viewer to understand if they wish to do so. If it doesn't appeal to their palate - they won't care.
So my point is, there is no grandiose glory to be had just because you "actually concentrate"d on the film to understand it. It just means that you had to make yourself understand it.
