Nirvana Was NOT and Still is NOT a Good Band

This might piss a few people off but... what's the big deal with Nirvana? Why do so many young people think that they are fantastically great?
Most of the younger people that listen to them only listen to them because their friends tell them they're great. Those friends really only think Nirvana is cool because Kurt Cobain killed himself. It is a simple truth. Same goes for SOME (I stress SOME) of the people that like Sublime.
I've questioned a few that like Nirvana. I asked a friend that liked Nirvana if he liked Pearl Jam, he told me no. This came as no shock. It just shows he was following the trend of liking Nirvana. Why do I say this? Nirvana started AFTER Pearl Jam. Nirvana sounds no different than any of the other grunge bands that came out of Seattle.
When you ask some of Nirvana's young fans who were born AFTER the grunge movement they will tell you that they don't like Pearl Jam and other grunge bands, yet they WORSHIP Nirvana. This makes no sense. It really blows my mind. I'm not trying to preach the whole "don't follow mainstream" thing. But come on! If you're gonna like Nirvana, you have to like one or two other grunge fans or you're just a fan because Cobain killed himself.
Post mortem popularity. Now isn't that a bit morbid?
