To me, E:E provides a sensory experience and grandeur not offered anywhere else.
How? May I ask for specifics? I would just like to know exactly where you are coming from. Is it the queue? The Yeti? The backwards sensation?
You say not offered anywhere else, but like it has been said before, the yeti is in the Matterhorn. Hell, I was riding Colossus backwards in the 80's and Revenge of the Mummy has the backwards thing going on already before EE had it. So, technically, it is offered somewhere else.
EE suffers from the same thing that the MK does. It's not the original, and Bigger doesn't always = better.
