I've never liked them and chances are I never will. I've never understood the appeal for that genre of music. While I don't like classical or opera, I can understand the appeal to it. Same way I can understand why people enjoy country music. But "grunge"? I... don't understand why people like it. At all. Much like rap for that matter. But we're talking about music so rap doesn't count.
A better comparison I guess would be Kubrick and A Clockwork Orange. I think it's one of the worst movies ever made and complete garbage but a lot of people seem to worship it for being some godly marvel. I have no idea why.
My dislike for the beatles is probably because I'm from Liverpool and grew up with them so they're just a normal unlikable band for me. Give me some Queen and Meatloaf and I'll be happy.
