There are so many other dimensions to the video media, conveying messages both overt and covert.
Background music creates a mood or blends scenes together.
Sound effects make things seem to have happened when they really didn't. Delay and reverberation convinces us that the action is taking place in a huge room or a tiny cell, not a TV studio. Light and shadow form another dimension preparing us for a message of cheer, romance, inspiration, gloom, mystery, or the surreal. Each of these dimensions communicate a mood or an environment. Camera angles are just one more dimension, one more tool in the director's bag of tricks for expressing an idea without actually saying the words.
