This is a much better team, with a better manager, but this has always (or at least has for my lifetime) been a cynical and knowledgeable fanbase that mocks the gullible true believers that one finds following the RS, United, Chelsea, Newcastle etc, which will not tolerate laziness, incompetence or ineptitude and which will absolutely be vocal in this.
If Goodison gets angry at opponents then its a great place, but too often it is aimed at the home side / specific players and recently (at least pre-Carlo) its become almost like a reflex because we are so used to relative failure that we expect it. "Everton that" is a joke but its probably the one thing about the club we all genuinely believe.
