Let's say you got an great looking effect. And you wanna sell it. This is not how to do it:
Shaky camera, footage all blurry, way toooooooooooooooooooooooo much shit going on that distracts from the effect. Too long, too desaturated, too boring.
A lot of attention went into the sound of this video, adding a nonexistent sound at the moment of the effect. But the picture got the ugly treatment.
