This is actually a pretty neat scale, but perhaps not too useful as to weather or not you personally like the attraction. Things I ride often but don't nessicarily believe are all that great include Carpets, Winnie the Pooh, Astro Orbiter, etc. Sometimes you just like something because it is what it is...
whereas I believe Country Bears, the old Tiki Room, Alien, and now Stitch are probably what I would define as 'cult attractions' - they may not always 'do it' for me, but I can see their merits. Whereas I'd rate things like Living With the Land, Tom Sawyer Island, Universe of Ellen, El Rio del Tiempo, etc as 'underdog' attractions. They're some of the best spots on property, but are often passed over.
But Grizz makes a good point - how do you rate something like a Jungle Cruise? How do you rate Dumbo? How do you rate something that's intended to be nothing but what it is? Perfect example: how could you rate the Skyway using this criteria? How could you rate the old Main Street Cinema using this criteria?
Still, it's an intriguing formulae, and one I can't say I won't refer back to. still, and I'm not saying, Grizz, that you had presented it otherwise, but it should not be regarded as a definitive formula for rating an attraction - and really, I'm not sure it should replace just a gut feeling, either.
Out of pure curiosity: was the scale devolped as a response to SGE? it seems logical as the show is frankly a 'problem attraction': one I delight in, but it defies easy categorization, and often feels half-formed the first time one expirences it. If your response to the show was to work out the rating scale that logically addresses what traditionally goes into a 'classic', then I applaud you for such an intelligent reaction: that was my inital reaction too. As in: "I think I liked that, but I kind of didn't, but perhaps I wanted to?"
Well, I do like it, but this scale very nicely brings out the strengths and flaws in most attractions, if applied objectivley. bravo!
as an aside, I'd simply like to address something brought up in earlier posts: the Haunted Mansion has absolutley no significance behind it's obvious plot arc: you enter a haunted house, it turns out to be a retirement home for spooks, and they throw a party. Coates, Anderson, and other Imagineers initally tried to 'crack' a story in regard to the show, but could never get far. Davis' innovation, once he climbed aboard after he finished his work on Pirates, was to give it no plot - just a succession of errie vingettes increasing in intensity and elaborateness. The Haunted Mansion is a symphony of atmopsherics.
It wasn't until Phantom Manor appeared, and those same unrelated vingettes were attatched significance, that folks began to speculate about what actually happened in that old house. I can say without hesitation that I think attatching such significance can be actively dangerous: the very thing that drives the show is the sense of mystery and of exploring half-grasped, dark secrets. To paraphrase Hamlet, you're going to pluck the heart out of the mystery.
Objectivley, on Grizz' scale, I can't give the Mansion's plot more than a 15/20. Phantom Manor gets that 20/20.
