Ever wondered why dance is so very special? Ever pondered over why dance is so emotive and connective?
This is why,

because dance epitomes powerful muscular story-telling. Dances creates a motor reflex/reaction in her audience and this reduces the gap between the performer and the audience. Some dances are worth watching over and over again, like this one:

Kinetic beauty is very much captured in this dance sequence and the dancers are all very committed, at least physically they are. We have no way to addressing the dancers' state of mind or mental intensity given the genre of the dance. But, the movements are so beautiful, so well crafted and so intense I have to watch it over and over again. There is also powerful use of beats and emphasis, the concept of weight-shifting to achieve intended muscularity.

And this is the real reason why dance is great:
 the dancers' flexibility or bodily control. Not every dance requires the dancer to be graceful or strong in their movement. Some dances, like this one:

requires a different kind of intend.
The dancer has to lok purposefully ugly. Tensed muscles. immense control and knowledge of the body is essential. There is a gradual degradation of the basic assumption of a human-form. This ugliness reflects life on many levels too.

Thus, dance is great.
