Did you ever see it work? 99 percent of the people on here havent.
Everyone has their own opinion, and you are certainly allowed to yours.
To me its still the best story coaster in the world. Especially for people that have no idea what the ride is and dont know it goes backwards or what will happen. The re-rideability is super high, its one of those rides that you can just go again and again. The theming is spot on. You could have the same effect with just sound through your headset in the seats, I think some disney fans just want to complain about something. To say that one effect makes it either at 10+ or a 2 is ludicrous.
Everest is still super popular and the yeti hasnt worked in decades, so clearly it hasnt hurt its popularity, and look at the smiles from the people that get off.
