The vaccines comparison just doesn't work. A vaccine cures a disease. The original Tiki Room can hardly be compared to a disease. The UNM show could be though lol!
More like we're going back to how it was before a new disease was introduced. UNM wasn't a vaccine, but rather an injection of advanced bird flu (see what i did there?). I'll take the original over that, even if it doesn't address any attendance problems. A newer GOOD would be better, but it was never in the cards anyways apparently.
I am well aware that SSE's descent was never finished. That's part of the inherent problem with the Disney company though. They build attractions in a half hearted way and don't finish them. I get the feeling this is what happened with Imagination's 1998 and newer refurbs as well. And it even plagues otherwise great and high-quality attractions like the new Little Mermaid ride in CA...
When they finish it, i'll pass judgement on their attempts. As it stands, we can only judge it as it is. Which is to say, pretty pathetic.
