Does anyone else feel that way?
So it seems to me that your problem really was that you don't enjoy listening to Chopin and Liszt regardless of who plays it. If that's your problem, why blame the kids who played at the competition? That said, I'm surprised you like Mozart and not Chopin/Liszt. That's a very good start! Most people immediately fall in love with the highly romantic music of Chopin and Liszt and usually take more time to warm up to Mozart and Beethoven. So hopefully you'll have started with Mozart slowly warming up to Chopin and Liszt later on.
