I understand the point of the video and I agree with it, but that guy (and everyone in this thread so far) is still wrong.
There is no difference between graphics and aesthetics. Gamers have made up this distinction when number of polygons and texture resolutions became a big deal. Truth is, define the word "graphics". Simply put, it means "visual representation". Sure, polygons and textures are part of that, namely the technical part. The other side is the art direction. Technical capabilities plus art direction = graphics = aesthetics = visuals. It's all the same. And yes, art direction has a bigger influence on a game's graphics than its technical specifications. That's the point of the video and it's all true. But stop mixing up these semantics. Graphics = technical capabilities plus art direction, period.
EDIT: damn plus sign not working *shakes fist*
