Get ready for a rant.
The queue is absolutely amazing, but the ride itself? Forgive me, but "meh."
With regard to the non-working Yeti, all I can say is, seriously, Disney? It's 2013, you employ well-educated engineers and you're making billions. Shame on you for not forking over the dough to fix the Yeti, or build a new, lighter-weight model that actually works! I know it will be difficult to shut down the attraction for awhile, but it's unacceptable to leave the centerpiece of the attraction in B mode, and so long as you leave it that way, myriad guests are going to continue to bypass Animal Kingdom completely because there's "not enough" unique things worth seeing there. (We have zoos at home. We have great coasters at our local Six Flags which go forwards and backwards. What we do NOT have is animatronic Yetis grabbing at us! Now
that is something I'd make the effort to see.) Even my six-year-old son, who' d been told nothing about the coaster before we rode, said dejectedly afterwards, "Gee, I thought there would be a Yeti someplace. The line [e.g., the queue exhibits] kept talking about it." At the very least, stop running those false and misleading travelogues on the Travel Channel about the Animal Kingdom, which spend half their airtime showing footage of the [working] Yeti, and the other half interviewing Joe Rohde's earrings about how awesome it is. It just makes you (and Joe) look ridiculous and deceitful, and creates false expectations in visitors.
I also didn't like that during the "backwards" section (on our visit in October 2012), I was able to look right into the inside of the mountain and see structural supports, etc. There is no reason Disney can't obscure this view with some rockwork or something, and it made for a "very poor show." Seeing the "guts" of the fake mountain shattered any illusion that we were on a real one.
Is Expedition Everest a respectably good coaster? Sure it is, but what Disney continues to promise to visitors is an excellent one with an amazing special effect at the end -- and it fails to deliver.
