I have a strong aversion to popular stuff too. Not as extreme as you , but for example I watched breaking bad 8 years after it came out and I was like damn that was good. I just couldn't watch it while everyone else went on and on about it.
Never have liked most popular music unless its from an earlier era. I can't name 1 new popular song from today. Ive been like this since I was 6.
Never liked new games everyone went on and on about graphics when I was little and I'm like, I dont care , new games suck.
I'm better now at being receptive. But I still cringe.
