That prelude along with no.2 is perhaps the most disliked compositions by Chopin. No.14 is simply an octave game in a tempo and melody that is not far from the Sonata Op.35's last presto movement.
I love all three of those!
I used to dislike the 28/2, but I really like it now. I've always loved the 28/14 and the Sonata 2-4. Just the fact that something monophonic can convey harmonic complexity is cool, to me. I don't know that I would say it's 'simply' an octave game, either. That's kinda like saying a good fugue is 'simply' an imitation game.
But yeah, it's stuff like this that caused Chopin's contemporaries to sometimes refer to his music as 'atonal', for sure.
