Fantastic post ! The kind of which has me work on my English too to get the whole of it. (this is where I reach my limitations too, sadly)
Just this :
Now to me, mere fact that I can identify a meaning system at least partially unique to wrestling is enough to constitute it as a medium with the potential to produce art, not to mention the issue of execution. Even acknowledging that the vast majority of wrestling probably re-inscribes conventions and that there a relatively limited set of stories that can or are told through wrestling (again, mostly by convention), the notion that this is a form which translates stories, characters and emotions through its own somewhat unique meaning system is enough for me. There are those who do it well and there are those who do it poorly and yes that might be largely a matter of taste, but there is a physical craft to it, trends, region/cultural differences, and all that constitutes a form that is if not outright artistic it has the potential for art.
I would agree with this, with emphasis on the bolded part. I would also use the word "craftmanship" as far as to describe what pro-wrestling is.
But again, terrific post.
