I was glad that EO came back and I had a chance to see it. I was too young for it's first round. To me though, EO represented Disney.
For some reason, to which I am glad now, my mom taped the opening of Euro Disney. On that, they have a section of EO playing, and closes with MJ tearing open his jacket to reveal the white t shirt with the lightening bolt (is it if I remember correctly!) on it. Having watched that video many times growing up (I was an odd child), it just screams DISNEY to me.
However, it was nice that they brought it back for a little while at least. I think HISTA had become dated and had been in situ for some time. But it would be sad if they now just use that area for previews. Sadly, I think the Imagination Pavillion lost its way a long time ago, and it just seems like the whole area is goig further and further down that path.
