I mean look - it was the wrong choice of ride for what Dreamworld needed in a recovery phase. They needed a big coaster or other massive drawcard and sky voyager was not the right choice in that environment, and in that line of thinking, it kinda was a waste of money when they needed something big to turn things around.
As an attraction though, its a great addition, and not a waste of money at all.
Firstly its capacity really takes a load off the rapidly declining list of attractions. Secondly, it provides solace from the heat with a good 20-ish minutes of indoor and air conditioning.
As an attraction type, soarin' is still amazingly popular in Disney parks around the world. The new-ish installs in the Asian disneylands have obscenely popular lines. Its the ride that keeps on giving too - as we've seen, change the ride film, and the whole ride is a new experience again. The film cost is a small part of the overall cost, so longevity is a no-brainer, provided the machinery can keep up with it.
The experience itself is also great - it suits MOST age groups, from ages 3-100+ so its a great all-rounder family attraction. Sure, its not the greatest thrill, but not everything in a park should be.
Sky Voyager has a place at Dreamworld. Add to this the new Steel Taipan at that side of the park and it takes a lot of pressure off the struggling Ocean Parade.
I really can't comprehend, with all of the above, how anyone could consider it a bad addition in any way except perhaps the timing of when it was introduced, for the reasons mentioned above.
