Music, stories, movies, if well done (I mean if really well done), can transport us to a whole other plane of existence.
In movies, the three work together...I remember seeing 2001:A Space Odyssey and feeling like I just touched G-d.
I remember going to a concert and dancing all night long, and one particular song(!) which to this day makes the hair on the back of my neck stand up.
Reading Treasure Island or The Three Musketeers makes me feel like I'm 11 years old and on some great adventure. We forget the "real" world and we are vividly in some magical realm, where everything is possible.
Why is it so difficult to make great works of art? Maybe because all stories are personal truths. A few transcend that to epic universal truths.
There is also the accidental element. That unexpected thing, force, fate, whatever you call it, that pushes a "great" work to the "sublime" - "May the Force be With You". "E.T. phone home", "Wax on, wax off". "All those moments will be lost in time, like tears in rain".
And a small side-note - art does not always have to be complex & edgy!! it can be as simple as a flower, as poignant as a hug...
