I think (as many said) free jazz can be BEAUTFUL. But, I remember downloading a live coltrane album (live in Japan maybe?) that just too much for me. One of the songs was an hour long. I listened to it just to see if I could.
I remember somebody once said to me "what's this?" i said "free jazz" and they said "is that called that because it's free (as in no money)?"
Good jazz musicians don't sit waiting for time to wail, the most improtant thing is to listen to the other musicians
