I've been to every premier league ground and the atmosphere at most if not all (and yes even Selhurst) is average. Very average. Ours is no better or worse. When the team are winning it's great. Same as any other Premier League stadium. Sounds like a waste of time to me.
Although I concur that the away fans need moving into the East lower/South East corner, but been saying that for 12 years.
In my experience the atmosphere at Leeds is annoyingly good. Otherwise I think I agree with you. I recall a few visits to the fabled St James' Park where it was like a morgue.
