The results are in!
I got distracted by other things halfway through the competition, so I played only about half of the games. I haven't played any of the top 3, and in fact only one of the top 7 games, so I guess that there is still some good stuff for me to try out.
I'm flabbergasted by the fact that Their angelic understanding has scored an average of 5.99. I changed my own mark to a 9 at some point. There can be some disagreement about marks, of course, but I cannot imagine how anyone could score it below a 7. This piece has beautiful writing, interesting thematic content and does new and impressive things with its medium.
It's a difficult piece, sure; but if you don't understand something, just refrain from judging. As a judge, you are called upon to judge a work of art, not to tell us how much you "liked" the experience of playing it. If you don't understand it, you shouldn't be judging.
(Yes, I'm kind of mad at this injustice, and guessing at the motives and thoughts of the people who misjudged Porpentine's fantastic piece. Those guesses might be wrong. Enlighten me.)
