Oh, well - this happens everywhere... movies, music... or "the hottest 100 women of all time"
Media are paid to create fads. They do not have memory longer than 3-4 years. Don't expect fine taste from the masses.
Don't worry, I'm also suffering from the "why people around are so much into crap" syndrome. You get that when you have independent taste. I'm afraid no shrink can help us, it's a personality trait.
