I again yet again disagree. The stages don't at all look similar. It's true that since we had Ireland hosting it all 4 times, it ends up sharing a similar spirit, type. But Oslo 96 was definitely a very different hosting, very modern for its time since the voting was in a studio entirely made of fake screenings. And even Irish settings weren't that similar, the huge Millstreet hosting was definitely different to the intimacy of Dublin 95. Alas, Birmingham 98 and Jerusalem 99 have nothing in common with each other and with the past stages.
I actually think the 00s have way more similar stages. Apart from the ancient greek theater in 2006, I don't see much differences between 04, 05, 06.. and then 08 is a BIG copy of 07, Helsinki's hosting being technically speaking the best one by far far far far of the decade. It's going to be equivalent to what Goteborg 85 was for the 80s!
