Yes they are overrated. And no I don't like them.

What redeems them from being some of the worst muscians to be in a band that famous (lets face it, but the drummer is good) is that they wrote some very popular and succesful songs (even if I don't like them, I can see that).

I say they are over-rated because once a girl told me she thought that Kurt Cobain was the best guitarist ever. She was serious. I laughed at her.
