I'm totally the opposite. I love going to Upton Park because it retains the atmosphere of a proper football ground. It absolutely pisses on any new ground that I have been to (including the Emirates).
Oh and btw I've spoken to fans of other teams who love Goodison. eg a Coventry fan who somehow ended up at the home game vs Arsenal last season who said it was one of the best "football days" of his life... I guess he knows what its like to lose your proper home due to owners with dubious motives.
You'll get an easy split of fans from other teams who appreciate 'classic' grounds. Coventry fans will appreciate any ground as they're owners left them homeless. City fans I know still pine for Maine Road, and appreciate the history of Goodison, but having tasted the 'niceties' of the Etihad are swayed. You can appreciate and love things whilst still admitting that all things considered they're no longer optimal for their current use.
Tottenham and Villa are the best examples I can think of for classic grounds that go most of the way to meeting modern requirements, but even Spurs are moving on.
I've literally sat behind a post at Leeds, and spent 2 hours convinced I was going to die in a fire at The Dell, but the absolute worst ground I've been to was the Olympic Stadium in Rome. Its just not a football ground, and you get even less room per seat than at Goodison!
