I caught them at Download and thought they were terrible. I think I might give them another chance because with all the fuss there has to be something there, but I'm pretty backed up with listening at the moment.
I saw them for the first time at Download and they completely blew me away with their energy. I'd say they're the first decent punk band I've heard in a while. And I really like their lyrics aswell which you don't necessarilly appreciate from the first listen.
