I enjoyed it, as in "that was pleasant" but I would have been sorely disappointed if I'd waited more than the time it took to walk to it (forever -- do not be fooled by a lack of line near the fast pass guy -- you walk a mile before you get to the loading area!)
As for hearing of people who waited an hour or more -- yikes! I don't wait for anything for that long, but this is a super short ride, so weigh your options carefully.
Overall, I don't know. I liked the smellovision, and we had the good front row seats. I guess I was expecting something more impressive. It's not nearly as good as the local Science museum's Imax movie that zips you along the highway and coast -- and that one doesn't move! The difference may be that it's too choppy, with too many scenes edited (very abruptly) so that just as you're taking in the orange groves, POOF! you're somewhere else.
I liked it, but it's nowhere near the satisfaction level of a Tower of Terror or Rock n Roller Coaster or Mission Space.
